EoFF is certainly unique for having been around for so long, and it continues to grow, so it has a pretty obvious social structure set up. I've never really bothered to integrate myself into another community since joining here because it's simply too much work. The only other forum I've really been especially active in was one I and a group of friends started in high school. It was small, but fun while it lasted.
I've certainly browsed some other forums and thought people were, in general, assholes, but I'm sure that's not at all indicative of non-EoFF forums as a whole.
