Used to be one a little over an hour from me, and I'm neither a joiner nor very social myself, so that wasn't going to happen. Just looked and that one is gone. Nearest one now is 2 hours away and their facebook page is deleted. That leaves one nearly 4 hours away ... again, just isn't going to happen. If there were one in my community -- if, like the local UU church, it were a five minute drive or a twenty minute walk away -- I'd check it out. Might go once in awhile. Nothing would probably come of it though.

I think this is the problem with atheism, it's like herding cats. It's too narrow a basis to form a sustainable community around. This Atlanta-area assembly seems to recognize that, they have moved away from identifying specifically with atheism, their differentiation is they "don't do woo", don't discuss the supernatural, but if you're agnostic or theist and want to hang out, fine. Also, they meet once a month rather than weekly.
