Our little niche is we get the hackers signed up when they signup for hackathons. Big university hackathons need a lot of value to keep the cash rollin' in from sponsors.
In fact, I think ditch the whole "eHarmony for ..." metaphor, and go for more of a "From Hackathon to Dream Career" kind of thing.
Admittedly that's not a very poetic line, but it better portrays your vibe and doesn't make me react "another OKCoFounder/FounderDating/WhiteTruffle/etc ughh im not looking for an MBA/where are the coders?"
