Words are great. I love stripping them down, rubbing them with oil, dicing them up,
and combining them with parts of other words. So I propose to you a new word that I hope sweeps the Internets. Just remember you read it here first.
Gregarian Societies - From the word gregarious "living in contiguous nests but not forming a true colony". In the post MySpace era, where user blogs are the new web page, there will be all these small colonies of users with similar interests congregate but basically form clicks rather than communities.
I have Wired to thank for putting this idea in my head.
