We launched a similar app over the weekend (loved the idea of a cofounder meeting site), it's at <a href="http://findmycofounder.com/" rel="nofollow">http://findmycofounder.com/</a>. We based the design on the comment thread (well, most of it). We added searching by geography, skills, primary focus, etc. It's an evolving thing, so suggestions are more than welcome.
