Aside from this being really uncool, FounderDating doesn't really work anyway. I've done it. Gathering a whole bunch of people who have an idea they want to work on in one place doesn't lead to very many of them pairing up and ditching one of the ideas. It's a lot easier to meet future co-founders, potential hires, and potential bosses before you actually need them. That's how networking works.
I'm toying around with a free, open source solution to this problem that reflects its true nature. If you're interested in contributing, contact info's in my profile.
I think it's more likely to be effective than blind networking. Building an early team just a fundamentally hard problem with no single / quick solution. FWIW I've met very helpful (non-cofounder) people through the site. In it's capacity to be a more startup-specific linkedin, it's interesting.
