We're actually working on this at Sparkmuse. We call it Matchmuse, an e-harmony for cofounders. I'm actually glad this one was a joke, but it doesn't matter because ours will rock! Matchmuse generates introductions to other cofounders in our 1000+ member community based on multiple dimensions of compatibility (sounds familiar doesn't it?). Our goal is to help entrepreneurs, especially those outside of the valley, form their own core groups.
edit: If anyone here who would be interested in using it, we'd love to hear from you~
