News.Com Tech year in review, haiku style
"The end of the year is a time of reflection. This week, News.com staffers took a break from journalism, at least for a nanosecond, to write poems that summarized the year in technology.
Some themes that were on their minds: plummeting stocks prices, layoffs and the dot-com shakeout. They tried haiku, limiting themselves to five syllables for the first line, seven syllables for the second line and five for the third line.
Should News.com staffers stick to their day jobs? You decide."

MSNBC Experts probe Net’s natural defenses
"The Internet’s organic structure explains why it’s so resistant to random failures, but researchers now say those same features make it vulnerable to cyberattacks. The findings could help security experts strengthen weak links in the Net’s chain.
"They found that samples of the World Wide Web didn’t have a random structure: Instead, the connections exhibited a hierarchy similar to that found in naturally occurring networks such as trees and living cells, with a small proportion of highly connected nodes branching off to a large number of less connected nodes. The structure was the same at different scales, meaning that the results could be extended to the Web as a whole, they said."
"Although the structure is particularly well-suited to tolerate random errors, it’s also particularly vulnerable to deliberate attack, they said. If just 1 percent of the most highly connected Internet routers or Web sites are incapacitated, the network’s average performance would be cut in half, said Yuhai Tu of IBM’s T.J. Watson Research Center.
“With only 4 percent of its most important nodes destroyed, the Internet loses its integrity, becoming fragmented into small disconnected domains,” he wrote in a commentary published in Nature."Nature : Science Update The missing links
"In an exponential network, there is a well defined ‘average connectivity’ for the nodes: most are connected by a certain number of links, and only a very few differ substantially from this average.
Barabási’s team says that there is another common kind of network that has hitherto been neglected: the ‘scale-free’ network, in which there is no meaningful average number of links - no ‘scale’ to it, in other words. In a scale-free network the number of nodes with a given number of connections simply declines as that number of nodes increases. Many nodes are linked to the network via just one connection; fewer have two, even fewer have three, and so forth. Unlike an exponential network, there remain small but significant numbers of nodes with many connections."
"...a cyber-terrorist armed with a map of a scale-free network could deliberately focus their attack on the few most highly connected nodes. Knocking just a few of these out would disable just about all flow of or access to information for other users, breaking up the webs rapidly into isolated fragments. This is the Achilles’ heel of the net, say the researchers, and defences against e-terrorism need to concentrate on making key nodes invulnerable."

3rd Annual ARCUS Award for Arctic Research Excellence Inuit in Cyberspace: Practising and Constructing Computer-mediated Space
"Research on the use of Internet or Cyberspace in relation to off-line space and sociality is uncommon to address in Arctic anthropology. The general research that does actually deal with Cyberspace, however, focuses more on strict on-line behaviour without much concern for dynamics between on-line and off-line space and sociality. Thus, naturally avoiding the physicality of the Arctic regions, it leaves the research reported in this paper to approach a rather new area. While most of the on-line Cyberstudies undertaken deal with American or European users, they unintendedly create and sustain universal ideas that, however, do not necessarily apply to all Internet-users. Often they focus on Cyber-space as if it was a single social vacuum without any recursive bonds to Lifespace and physical space; operating in a mental paradigm, that assumes people to be without cultural differences in Cyberspace.
However, as this paper will argue, the world, the conceptions of it and use of space within it, be it Cyberspace or physical space, are clearly more than vacuums of mental space."

The New York Times Bill Gates Turns Skeptical on Digital Solution's Scope

"As the "Creating Digital Dividends" conference drew to a close in Seattle recently, the final speaker arrived and started asking skeptical questions. The premise was that "market drivers" could be used "to bring the benefits of connectivity and participation in the e-economy to all of the world's six billion people," according to conference materials, but the speaker would have little of it.
"I mean, do people have a clear view of what it means to live on $1 a day?" the speaker, William H. Gates, asked. "There's no electricity in that house. None.""
Pacing the room, waving his hands, he conjures up an image of an African village that receives a computer.
"The mothers are going to walk right up to that computer and say, My children are dying, what can you do?" Mr. Gates says. "They're not going to sit there and like, browse eBay or something. What they want is for their children to live. They don't want their children's growth to be stunted. Do you really have to put in computers to figure that out?"
O'Reilly Network The Case Against Micropayments
"Micropayment proponents have long suggested that micropayments will work because it would be great if they did. A functioning micropayment system would solve several thorny financial problems all at once. Unfortunately, the barriers to micropayments are not problems of technology and interface, but user approval. The advantage of micropayment systems to people receiving micropayments is clear, but the value to users whose money and time is involved isn't.
Because of transactional inefficiencies, user resistance, and the increasing flexibility of the existing financial framework, micropayments will never become a general class of network application. Anyone setting out to build systems that reward resource providers will have to create payment systems that provides users the kind of financial experience they demand - simple, predictable and easily valued. Only solutions that play by these rules will succeed."
I'Cringely I'll Gladly Pay You Tuesday
"PayPal's use of plain old dollars and its ability to send money to anyone with an e-mail address set it apart from the earlier payment systems. To that point people had to get together and agree on what system they would use for payment, then both had to be registered for anything much to happen. PayPal took more of the Western Union approach -- that if you were told that some money was waiting for you down at the Western Union office, you'd find a way to hike down there and get it. For PayPal recipients, hiking down means registering as users. It's free. It's actually better than free since full registration scores you a five-dollar bonus, as well as another five-dollar bonus to whomever refers you or is the first to pay you using the system. And that's how PayPal actually began operations last October -- with 24 employees sending small gifts of money to their friends."

First Monday Information Seeking on the Web: An Integrated Model of Browsing and Searching
"The research presented here suggests that people who use the Web as an information resource to support their daily work activities engage in a range of complementary modes of information seeking, varying from undirected viewing that does not pursue a specific information need, to formal searching that retrieves focused information for action or decision making. Each mode of information seeking on the Web is distinguished by the nature of information needs, information seeking tactics, and the purpose of information use. The information seeking tactics characterizing each mode were revealed by recurrent sequences of browser actions initiated by the information seeker. Thus, undirected viewing is characterized by starting and chaining actions; conditioned viewing is characterized by differentiating, browsing, and monitoring actions; informal search is characterized by differentiating and localized extracting; and formal search consisted of systematic, thorough extracting.
Overall, the study suggests that a behavioral framework that relates motivations (the strategies and reasons for viewing and searching) and moves (the tactics used to find and use information) may be helpful in analyzing Web-based information seeking. The study also suggests that multiple, complementary methods of collecting qualitative and quantitative data may be integrated within a single study to compose a more nuanced portrayal of how individuals seek and use Web-based information in their natural work settings."

The skeptical Internet user has made a return-on-investment evaluation of his Internet experience, and has come to the conclusion that the return on some sites is just not worth the investment of his personal time and energy."
"The skeptical Internet user did not come to the Internet because of his innovative attitude. His motivation is not to learn and use the Internet. Instead he is motivated by the Internet's promise of offering value: comfort of living, entertainment, getting things done in a more convenient way. While he did get some of that, he also got a lot of discomfort: long download times, navigational and structural complexity, inconsistency, unpredictable behavior, disappointing value."

Media In Transition What is Information? The Flow of Bits and the Control of Chaos
"Information science operates with a binary logic of reflection which results in multiple paths, but these paths are always circumscribed by laws of combination (Deleuze, & Guattari, 1987). In this manner the fragmented space and time of information flows is reordered and directed toward specific objectives. But the objectives of information processing within the capitalist dynamic are not end points-- they are aimed at an accumulation of knowledge that is always an impetus for further accumulation, for multiplying the flow, opening out into every horizon. But this flow is at the same time stored up in a central memory which traces the exact paths of this flow, connecting geographic spaces and matching up the temporal locations of dispersed market centers. This central memory system functions through command trees, centered systems and hierarchical structures that attempt to fix possible pathways of the network and thus to limit the possible variations immanent in the network. The definitions of information formulated within information science and information economics derive from and serve this modeling of the system. As we have seen, information defined as nonsemantic discrete bits flowing across space and then directed and stored substantiates information as the object of control. Thus, the enemy of the information scientists and economists is heterogeneity, disorganization, noise, chaos. They want an uninterrupted flow, but at the same time a destruction of the unnecessary. This encloses or territorializes information; it becomes a part of capitalism’s mapping of space and time. But what we have found is that information’s function is precisely to disorganize, interrupt, to remain itself and at the same time to disperse. Information may, in fact, be a keyword connecting the phenomenon we have examined, but not as an element, nor as a content, but as a heterogeneous remapping of space and time. If the information society is to be our society, let it be disorganized."

The Standard Home on the Web
"Home networking is nothing new. Homes are already thoroughly wired for lighting, security, phones and more. The Internet home will connect all of the in-home networks, then connect each with any number of outside networks. For the fridge to talk to the computer, at least two networks – the home electrical network into which the fridge is plugged, and the telephone, firewire or wireless network into which the computer is connected – need some way of interfacing. And if the fridge needs to send you e-mail at work, it needs some way to communicate outside the home network.
But the obvious question is, do consumers want all this interconnectivity? Will we ever really need our fridge to e-mail us that our milk is past its prime?”
"After IBM ran a series of ads in which a dishwasher repairman shows up at a home because the dishwasher contacted him for service, Parks Associates held focus groups to gauge reaction to the commercial. "Consumers absolutely hated that," says Scherf. "People want more control of their lives, not less; they want to be the one to make the call, not the dishwasher."

Fast Company Design Vision
""We know how to do amazing things," [Thackara] says, "and we're filling the world with amazing devices. But we cannot answer the most important question: What is this stuff really for?""
"The time has also come, he says, to shift some of the focus of innovation away from work and toward everyday life. The early users of digital devices are almost always business users, so product designers have a natural inclination to create and design products with the workplace in mind. But that tendency can make for bad design, especially when those products migrate beyond business. People put up with technical difficulties in their work lives that they would never tolerate in their personal lives. So forget "personal" computing, Thackara says, and embrace "social" computing. "As computing migrates from ugly boxes on our desks to something that suffuses everything around us, a new relationship will emerge between what's real and what's virtual, what's mental and what's material. There are few limits to the number of services that we could develop if we simply took an aspect of daily life and looked for ways to make it better.""

"Russell Robertson was grappling with an unusual assignment.
As an industrial designer, his mission was to figure out how kitchen appliances will be designed when, as he put it, "the fridge talks to the coffee pot."
His eyes twinkled as he spoke, but he was not kidding about the basic concept. In fact, while the idea may have once sounded ridiculous, predictions of the advent of such devices are now becoming almost clichéd."
"But predicting whether a technology will be adopted is critical for companies that want to succeed, or even survive, in the marketplace. The ones that can figure out what will be deemed useful, superfluous or downright ridiculous will win. And today, as tiny, wireless computer systems are being perfected and the Internet is allowing the distribution of data in seconds, dozens of appliance manufacturers are betting that some sort of pervasive-computing devices will come to be considered as necessary as a telephone. The trick, for them, is to figure out which ones."
""But one of the main reasons that companies with new products stumble, Professor Utterback said, "is that they fail to appreciate or investigate the marketplace." Many companies simply ask, "What can we do with the technology?" And once they determine what they can do, he said, they assume that people will want it."

Free Software Advocacy Against intellectual property
"The original rationale for copyrights and patents was to foster artistic and practical creative work by giving a short-term monopoly over certain uses of the work. This monopoly was granted to an individual or corporation by government. The government's power to grant a monopoly is corrupting. The biggest owners of intellectual property have sought to expand it well beyond any sensible rationale."
"This chapter outlines the case against intellectual property. I begin by mentioning some of the problems arising from ownership of information. Then I turn to weaknesses in its standard justifications. Next is an overview of problems with the so-called "marketplace of ideas," which has important links with intellectual property. Finally, I outline some alternatives to intellectual property and some possible strategies for moving towards them. "
"Intellectual property is supported by many powerful groups: the most powerful governments and the largest corporations. The mass media seem fully behind intellectual property, partly because media monopolies would be undercut if information were more freely copied and partly because the most influential journalists depend on syndication rights for their stories."
"Another problem in developing strategies is that it makes little sense to challenge intellectual property in isolation. If we simply imagine intellectual property being abolished but the rest of the economic system unchanged, then many objections can be made. Challenging intellectual property must involve the development of methods to support creative individuals."

What troubles me with this argument is the arrogant notion that human logic can anticipate the effects of intended or unintended acts, and the more arrogant notion that human reasoning can determine the course of the universe."
"I suggest we broaden our perspective to the fullness of our humanity, which besides reason includes feelings and beliefs. Sometimes, as we drive the car of scientific and technological progress, we’ll veer because our reason says so. At other times we’ll follow our feelings, or we’ll be guided by faith. Most of the time, we’ll steer with all three of these human forces guiding us in concert, as they have guided human actions for thousands of years. As we do so, we should stay vigilant, ready to stop, when danger is imminent, using our full humanity to make that determination. If we do so, our turning point will be very different from where it may seem today, based on early rational assessments...that have failed us so often. Let us have faith in ourselves, our fellow human beings and our universe. And let’s keep in mind that our car is not the only moving thing out there."

Wired Magazine Why the future doesn't need us.
"Biological species almost never survive encounters with superior competitors. Ten million years ago, South and North America were separated by a sunken Panama isthmus. South America, like Australia today, was populated by marsupial mammals, including pouched equivalents of rats, deers, and tigers. When the isthmus connecting North and South America rose, it took only a few thousand years for the northern placental species, with slightly more effective metabolisms and reproductive and nervous systems, to displace and eliminate almost all the southern marsupials.
In a completely free marketplace, superior robots would surely affect humans as North American placentals affected South American marsupials (and as humans have affected countless species). Robotic industries would compete vigorously among themselves for matter, energy, and space, incidentally driving their price beyond human reach. Unable to afford the necessities of life, biological humans would be squeezed out of existence. "

"For nearly five decades, artificial-intelligence researchers have tried to build robots of human-level intelligence. In 1956, Allan Newell and Herbert Simon, creators of the first artificial-intelligence program, predicted that machines would soon be capable of understanding and translating spoken language, composing classical music, and inventing new mathematical theorems. This would happen, they said, by 1970.
Recent predictions about the trajectory of machine intelligence have been no less heady. Futurists speculate that robots will soon clean our houses and baby-sit our kids. They will run factories and fight in wars. There will be robot sonnets, robot paintings, robot symphonies. They will surpass us in intelligence and inherit the earth.
Canadian roboticist Mark Tilden calls this scenario "Attack of the Killer Robots" and dismisses it as pure fantasy. Unlike most AI researchers, Tilden isn't interested in creating a robot as intelligent as a human being. He just wants to build one that's as smart as your average bug."

FightAids@Home Overview
"Now more than ever, you are needed to help in the fight against AIDS. In the mid 1980's HIV infections reached epic proportions and have since continued to rise at alarming rates. Nearly twenty years later, technology has reached a point where you can make a difference by contributing the idle processing time of your PC.
Here is how it works:
To support FightAIDS@Home, you simply download a free software program from Entropia that runs "in the background" on your computer. FightAIDS@Home processes information (in this case using AutoDock) and calculates prospective targets for drug discovery. Basically, what this means is that FightAIDS@Home uses idle processor cycles that would normally be wasted. FightAIDS@Home captures the otherwise wasted cycles of your PC and applies them to model the evolution of drug resistance and to design the drugs necessary to fight AIDS. When your computer has finished a FightAIDS@Home computation, the FightAIDS@Home results are packed up and sent back to Entropia, ready for Scripps researchers to collect and analyze them.
Then when you are using your computer and it needs cycles, FightAIDS@Home simply and automatically turns those resources back over to the program you are using.

"The SETI@Home problem can be thought of as a special case of the distributed computation verification problem: "given a large amount of computation divided among many computers, how can malicious participating computers be prevented from doing damage?" This is not a new problem. Distributed computation is a venerable research topic, and the idea of "selling spare CPU cycles" has been a science fiction fixture for years.
In real life, distributed computation has been used since at least the late 1980's to create "farms" of machines for rendering 3-D images. Farms allow graphic artists to create large images without needing to buy a supercomputer. More recently, the needs of scientific computation have led to the creation of frameworks such as Parallel Virtual Machine (PVM) and Beowulf, which make it easier to distribute computations across many machines. The machines involved are usually owned by the same entity and a machine is either "good" or "bad" if it is operating or malfunctioning. There are no blatantly malicious machines.
The Internet makes it possible for computation to be distributed to many more machines. However, distributing computing around the internet requires developers to consider the possibility of malicious clients."
"The general study of secure multiparty computation has produced much interesting work over the last two decades. Less well studied, unfortunately, are the tools and techniques required to move the theoretical results to the real world. The old dream of massively distributed computations is finally coming true, and yet our tools for building and analysing real systems still seem primitive. The challenge of the next few years will be to bridge this gap."

"A natural complement to distributed file-sharing capabilities is distributed computation. The idea behind distributed computation is that a really big problem gets split into discrete, independent chunks, which are then parceled out to individual computers whose owners have volunteered their idle processor time to the cause. In aggregate, the users' computers form a sort of distributed supercomputer. The concept was first popularized by U.C. Berkeley's SETI@Home project, a 1999 PC Magazine Technical Excellence finalist that's now been downloaded by more than 2 million users. Though SETI@Home is a single-purpose tool designed solely to scour radio-telescope signals for signs of extraterrestrial transmissions, you can expect to see general-purpose mechanisms for distributing all kinds of massive computations. United Devices, for example, is a company that will use distributed computing for projects in areas such as bioinformatics research, drug design, and climate studies."
The Standard Distributed Computing Goes Commercial
"The distributed-computing model could be one of those rare cases where capitalism and pure scientific research mesh. Not every lab can afford to pay $200,000 for an eight-processor Origin 2000 SGI supercomputer, much less $1 million for a 40-processor machine, says David Fenstermacher, director of scientific computing for the medical school at the University of North Carolina at Chapel Hill. (Fenstermacher is also acting director of the campus' Center for Bioinformatics and a United Devices adviser.) And even the most powerful supercomputers need time to process data.

The Edge One Half Of A Manifesto: Part II
"Jaron Lanier responds to Reality Club comments on the .5 Manifesto by George Dyson, Freeman Dyson, Cliff Barney, Bruce Sterling, Rodney Brooks, Henry Warwick, Kevin Kelly, Margaret Wertheim, John Baez, Lee Smolin, Stewart Brand, Rodney Brooks, Lee Smolin, Daniel C. Dennett, Philip W. Anderson."
Salon Artificial stupidity
""Software is brittle," he says. "If every little thing isn't perfect, it breaks. We have to have an honest appreciation for how little progress we've made in this area."
On the surface, Lanier's stance appears to resemble that of Joy, the influential programmer who used the pages of Wired magazine to condemn Moravec and others for desiring to build sentient machines without acknowledging the apocalyptic dangers. But Lanier ultimately takes quite a different tack. Joy condemned science for what it could do; Lanier condemns it for failing to recognize what it can't. Lanier's upstart argument yields a uniquely here-and-now version of computer science ethics and an entirely different, but equally frightening form of what Lanier calls "Bill's version ... of the Terror.""

NetFuture THE TROUBLE WITH UBIQUITOUS TECHNOLOGY PUSHERS (PART 3)
"If we do not pay attention to the difference between the computational abstraction and the human reality in the simple cases, nothing will require our attention to those differences in the "higher" cases.
Further, the more you automate, the more you tend to reduce the affected contexts to the terms of your automation, so that the next "higher" activity looks more and more like an automatic one that should be handed over to a machine. When, finally, the supervisor is supervising only machines, there's no reason for the supervisor himself not to become a machine.
So the idea that automation relieves us from grunt work in order to concentrate on higher things looks rather like the opposite of the truth. Automation tends continually to reduce the higher work to mechanical and computational terms. At least, it does this when we lose sight of the full reality of the work, reconceiving it as if its entire significance lay in the few decontextualized structural features we can analogize in a machine. (In a machine-driven world, we are always pressured toward this reconceptualization.) But if, on the other hand, we do not lose sight of the full reality of the work, then the "lower-level" stuff may look just as much worth doing ourselves as the "higher" -- in which case we have to ask, "What, really, is the rationale for automating it?""

MIT Technology Review Not by Reason Alone
"In a recent Wired magazine article, Bill Joy argued that the consequences of research on robotics, genetic engineering and nanotechnology may lead to “knowledge-enabled mass destruction...hugely amplified by the power of self-replication.” His medicine: “relinquishment...by limiting our pursuit of certain kinds of knowledge.” I don’t buy it.
What troubles me with this argument is the arrogant notion that human logic can anticipate the effects of intended or unintended acts, and the more arrogant notion that human reasoning can determine the course of the universe."
"I suggest we broaden our perspective to the fullness of our humanity, which besides reason includes feelings and beliefs. Sometimes, as we drive the car of scientific and technological progress, we’ll veer because our reason says so. At other times we’ll follow our feelings, or we’ll be guided by faith. Most of the time, we’ll steer with all three of these human forces guiding us in concert, as they have guided human actions for thousands of years. As we do so, we should stay vigilant, ready to stop, when danger is imminent, using our full humanity to make that determination. If we do so, our turning point will be very different from where it may seem today, based on early rational assessments...that have failed us so often. Let us have faith in ourselves, our fellow human beings and our universe. And let’s keep in mind that our car is not the only moving thing out there."

Reason Joy, to the World
"... Joy is worried, really worried–20,000 words and five months of writing worried–that 21st-century technologies threaten to make human beings extinct. The threats are intelligent robots, nanotechnology (the ability to build things on the atomic level), and genetic engineering. All of them, he acknowledges, offer wonderful advantages, but they are, in his view, simply too dangerous to develop. We should stop investigating these ideas, he argues, before they become uncontrollable realities."
"Bill Joy is a lot smarter than I’ll ever be. But he is also incredibly foolish, in the parochial, reality-dodging way that geniuses sometimes are. And he is willing to sacrifice an awful lot of other people’s lives and liberty to his fantasies of power and control.
If—then statements are a staple of computer programming. Here’s one to consider: "If we could agree, as were headed, and why, then we would make our future much less dangerous–then we might understand what we can and should relinquish." (Emphasis added.) How, exactly, does a species of more than six billion intelligent individuals, with their own plans and purposes, agree on anything? Joy imagines the world as a small, technological elite and assumes away the problems of politics. He and his friends will just get together and agree on what to do."

Wired About Those Fat Net Mags
"Lugging around a couple of magazines that cover the Internet and technology industries might qualify as a workout these days, with their bulked-up editorial staffs churning out a record number of pages to keep up with demand for advertising space.
The trend, which shows little sign of slowing despite a nascent dot-com shakeout, has at least some industry watchers wondering if these publications are growing a pace that may be setting them up for a big letdown -- just like some of the once high-flying companies they cover. "
""We believe it's not a good thing being a fat 400-to-500-page vehicle. We don't think readers want that," said Steve Thompson, senior vice president and group publisher of the Industry Standard."

"It's no great mystery what's fueling the ungainly growth in these magazines. "There's a huge information overload going on right now," says venture capitalist Andrew Anker, a partner at August Capital. "It's being driven by marketers trying to spend dollars, not by users saying 'I need this content.'"
Web companies spent more than $700 million on magazine advertising alone last year. That's 348 percent more than they did in 1998, according to Competitive Media Reporting. Plus, with almost $25 billion flowing from venture capitalists into Net companies in 1999, 66 percent more than the previous year, there's a lot of business-to-business advertisers itching to reach the newly cash-rich dot-commies who need to quickly find somewhere to put all that capital to work."
""Are we too big? Of course, we're too big," says Jason Pontin, editor of the Red Herring, which is putting out a whopping 488 pages in April. "I recognize that we're getting uncomfortably large.""
MSNBC Plenty Wrong With WAP
"Try this experiment: pick up your newspaper and find the weather forecast for your area. Note how long it took you. Look up the listings for the movie theater closest to you. Find a sports score. In each case, record the elapsed time."
NOW TRY THE same thing on a mobile telephone using a technology called Wireless Application Protocol, or WAP, to access the Internet.
You already know the result, don’t you? Everything will take longer the second way."
Alertbox WAP Field Study Findings
"Following a UK field study, 70% of users decided not to continue using WAP. Currently, its services are poorly designed, have insufficient task analysis, and abuse existing non-mobile design guidelines. WAP's killer app is killing time; m-commerce's prospects are dim for the next several years."
"Mobile services must target users with immediate, context-directed content. General services like shopping are less likely to succeed in the mobile environment. Indeed, in the list of services bookmarked by users, shopping hardly figures at all; sports and entertainment are the two big categories.
Killing time is a perfect application for mobile devices because they are readily available when users are waiting around for something to happen. At the bus stop? Play a short game. In line for something? Read a paragraph of gossip. Stuck in traffic that doesn't move? Check the scores of your favorite teams."
ClickZ Give WAP a Chance
"We don't need to be told that WAP has not yet set the world on fire, especially when we've only seen the tip of the mobile Internet iceberg.
It's been obvious to most in our industry that WAP has not lived up to everyone's expectations. It's been oversold; the public is feeling let down -- it is not the "mobile Internet" promised by BT Cellnet and company; and the digital media industry has been quick to turn about-face and join in WAP bashing. But we believe there's been too much negativity, and the overselling has now hindered acceptance of the positives that have undoubtedly come out of the "2G" explosion.
There are some types of WAP services and sites that are genuinely useful."

The Standard Deconstructing the Web
"The Web is disintegrating into bits. When the dust settles, what's important for a successful long-term strategy is not Web site design but the flexibility of your information architecture."
"New Internet devices and applications are different not only because they are designed to do different things, but also because the mindset of the person who uses them influences the kind of interaction that makes sense. You cannot shove a Web page onto a cell phone's tiny screen. Even if you could, it wouldn't make sense from the user's point of view. The information I want delivered to my cell phone is different from what I want on my home computer. Web pages are designed for sedentary, reflective use. The phone is for urgent, short communications."redux [06.15.00]UIDesign A WAP On The Knuckles
"The knives are out for WAP technology. Following the huge hype of the last 12 months, it's becoming apparent that it just isn't delivering. Naturally, the naysayers have now become the "told-you-so-ers". However, the disappointment of WAP technology needs some more careful analysis. The industry deserves a good wrap on the knuckles. Much of what has happened was avoidable. Will the lessons be learned?"
"The biggest single mistake was to take the view that an internet enabled phone is a general purpose device. It was an easy mistake to make. A computer with web browser was a general purpose device. You can use it to surf any web site. A phone is also a general purpose device. You can use it to call any number. However, when you put the two together, the combination is limited. To be completely general purpose it would need to have a keyboard, a full size screen and a phone transceiver built in together. It would need to be both a computer and a phone, i.e. a laptop with a phone built in. Current WAP Phones are still phones, but they are NOT computers in the sense of a PC. This was the first mistake - marketing the device as if it was a computer.
A WAP Phone is an "invisible computer" or it ought to be. A WAP Phone thought of as an invisible computer, becomes an information appliance. Furthermore, each different form factor of WAP Phone is a different information appliance. The whole industry failed to realize this. Information appliances should be designed for a specific purpose or a limited set of purposes. In other words, with current technology, the "walled garden" approach was correct providing what was inside the garden made sense for the specific information appliance, as a single product."
