Just added smartmobs.com site dedicated to a book by... Howard Rheingold, (took me awhile to figure out who the author was.), who the site claims is "one of the world's foremost authorities on the social implications of technology" ($18.00 at Amazon) He used to edit The Whole Earth catalog and lives in Mill Valley, CA if that tells you anything. (Me and my hippie mummie used to subscrbe to the catalog and also used to live in Mill Valley if that tells you anyhting more!)
