I like the idea, really, but I'm afraid it'll just become another version of the polls subforum. -_-; That and the introduction forum.
Here's my question to you. How would you distinguish this from becoming another area to plop down a few words and be on one's way? What will you do to encourage people to engage in a conversation with each other? And what's stopping it from being entirely self serving, where people just post about themselves but never respond to anyone else in that same subsection?
If you can find some solutions to that (not looking for miracles, of course), I'll be behind you 100%.
