Another issue I've found with online communities is that they generally focus on a single thing. It's great when you just want to talk about that one thing, but I don't think it's a great way to make friends. Twitter is interesting to me because it's a network rather than a community, but there often seems to be a weird power dynamic between people which would also stifle friendships.
