This isn't my project but something that some people I know are trying to get going. I think they are almost shooting for a dating site type feel - I've had the process of finding a cofounder refered to as dating (with the hackers as the women in this analogy).

It is early but I believe they're trying to get user feedback so they can iterate. As it says on the site this was built at a startup weekend event. They can't improve the UI and features without having users providing feedback.

I agree they could have more fine grained control of location, although I believe that MA would be covered by the Eastern US region.
