I think people got busy with their lives and tired of the same conversations with fewer people.
Btw, Deb: the rest of this thread is on the Politics forum since the responses devolved into politics. Maybe if we keep the political discussions on the politics portion of the forum some people might feel more comfortable posting here again. I know I'm totally turned off when I see an alleged critical thinking forum has turned into one or two people shouting in an echo chamber. The social board was always meant to be free from politics, ad homs, etc so let's keep it that way.
