I've been thinking a lot about virtual community -- are they even possible? I'm finding that I'm a lot more comfortable talking online with people once I've met them in person. Surely this isn't the way it was supposed to work? People have been tackling these issues for years, but there's no sense of history on the internet; there's no debris, no cruft and accumulation, no way to tell that groups have made these journeys before. How to build "community"? And what is it?
