Part of me wanted to tag this as a feature-request, because it would be nice, but I feel that if plans aren't already in place for this, then it isn't too wise to try and scramble it in.
We're only as far as the commitment phase, but I've been reading about the plans for when sites hit the closed beta. That's when we discuss all the colorful details of the future site, such as its real name, the FAQ, tagging nature, and other design stuffs. I agree with the idea of delaying this discussion until that stage, but then I started to wonder, "Where is this all going to happen?"
Are there plans for having the "Third Place" available by the time some of the sites are ready for the closed beta? Will we be able to use it for these site-detail casual discussions, allowing real-time deliberation on our subjects?
