Ning is Love
http://www.ning.com

Basically, it's a site that's set up so anyone can make up their own custom social networking site. I promptly found P.O.W.E.R. in Comics, which has an emphasis on women and minorities in the field of comics (hey, I'm both of those!), and joined. It only has 101 members, but I'm just excited to find a place about comics that I can feel at home at. My page is here.

I wonder what else I can find on Ning...
