i really don’t think i can add anything to matt’s characterization of “bridging the bubbles”:
” Browsing blogs, I’ve often had what I call the “glittering cave moment”; when I leave the dowdy, familiar surrounds of my blog-neighbourhood and get taken by the hand (or link) by someone I trust into a new and sparkling world of scary new knowledge, opinions, thoughts and views. That bridging moment has a tangible excitement to it.”
