You're implementation still feels like a slight twist on what we've seen before. You list criteria which are used as filters, and you either show interest or don't. OKCupid is pretty much the same thing. Sure, you take away the profile filling, and uploading photos part, but it's still the same thing, but slightly different. Thing is, after a match is found, you don't solve the "well shit, what do I do now?" problem. You're back to awkward and possibly creepy part of messaging and setting something up.

I remember seeing a very interesting idea for a dating website a while ago on HN, where you're matched based on activities/events you're interested in going to. I really liked the idea, as it matches based on interests, and it automatically answers the what-are-we-going-to-do question.
