Not a terrible idea, I was trying to think of something that fits nicely into the gossip/anonymous board idea. Like maybe a post-secret type section. Errr... well, I'll think about it some more.
I personally think this is a great idea. Reading through the posts, its obvious that this offers something that juicycampus does not, mainly, actual conversations. You might consider expanding tools, I notice you can private message people, which is cool, but it would be nice if there were a couple "special" reasons to come to your site other than what I just mentioned.
