Yup, doing both here, too. Was hoping for another halftime wardrobe malfunction, and getting close to having invite codes ready: http://yak.to
Perhaps you could put at least some sort of teaser on the homepage as to what problem you might be solving or at least some clue as to the problem space.
I've been inspired most by Reddit (thanks again jedberg), but Yak is more playful, flirty, and local.
If you pass an invite code, I'll be glad to play with it and report bugs I run in to. My email is in my profile.
