In a facebook message with Jeff Grossberg:
Regarding community tools... I'm glad to see technology not being used solely for money-making but also for friend-making.
Fundamentally, community has changed. Most of us will never have the nostalgic small village existence that is imprinted in our deeper social patterns. We are too mobile, absorbing too much news from too many sources, and interacting with too many people flung too widely. Our social fabric has been stretched beyond its former limits, so it is high time that we learn new ways of weaving it.
