The shocking thing to me is that they have a LiveJournal community there with a few hundred users on it and I didn't recognize a single one. Not one single person. Sure, that might not seem so odd to many of you, but for me, that's just fundamentally not right.
For those who haven't been assimilated yet, I suggest you snag an account while tribe.net is still in beta. Vulture capitalizsts are talking about such apps as if they are the next big thing. Which they are, in a way... but really, I suspect that they will be in a way that doesn't necessarily entail a whole lotta profit. That, incidentally, is a good thing. Selah.
