YC-Local?

There seems to be a yearning on yc for people to find e/o or just talk to people near them. Why not have local channels for meetups etc? Could be in the form of sub-forums or you could submit a link as local and only those who subscribe to a region in their prefs would see it. Not very creative but I've only slept an hour. Let's hear you ideas. I know the demand is there.
