True story: I worked for OkCupid Labs a few years ago and we made "Hater Dater" as a hack project. The concept was kind of a joke, but we actually ended up extracting a useful tagging library that we used in other projects. I put a little more time into it after the Labs was closed, but never thought it worth putting _that_ much effort into. So it's amusing to see someone working on this project in earnest, with funding, when internally we couldn't get the OKC/Match/IAC resources to play with it for longer than a week (which honestly is probably the right call). Maybe the moral of the story is that life is kind of a joke?
