a very interesting site through Derek Powazek‘s site this evening: CommunityZero. Anyone can set up a free online community for their friends, for a project, whatever. Many of these have come and gone in the past, but none quite as well executed as this one seems to be. I may play with it soon – as a long-time online community guy, it has been a goal of mine to merge this site with a series of discussions at some point.
