Cool,
I've only belonged to one other board...a computer builder's message board. They had an "Off-Topic" sub-forum that was very tightly moderated. They did not allow
ANY controversial topics to be discussed. I kept getting warned because I kept bringing up controversial topics.
Eventually, they developed a "sister" site, so those of us who wanted to discuss politics, or other similar topics, could. The site sucked, big time. Little activity, less intelligence. So, I Yahoo!ed (I can't stand Google) "debating politics" and I found several sites that were interesting. Debate Politics was, by far the best. I "lurked" without registering for about 3 months and, then lurked after registering for another 2 months before I made my first post. I think the two biggest drawing points to DP were the interesting people/threads and the fairness and balance. Also, the activity level here is awesome...always someone or something to talk about.
