But people don't stay anonymous. They create a persona and identity to help establish them as a "regular".
I'm a fan of the way this forum works though.

You can more or less create a username that only you can access but you don't have to use it when you don't feel like it.
I spam my referral link there sometimes now but I've been with them since they were small. There is almost zero staff and activity has ups and downs but it's never as dead as we are. They also have no real focus. Literally, there is just a sub-forum for everything and a chat feature. Each sub-forum and the chat rooms have a a population and culture all their own. It's really interesting honestly. If I ever decide to go back to school to get a degree in something entirely else I'll have to go with sociology or behavioral studies so I can study and write about forums and the behavior of their users.
