Submission + - Genetic Based Match Making (okcupid.com)
Cirvam writes: "According to this article, the online dating site okCupid is now requiring users to submit a blood sample to be matched properly with their new matching system. Supposedly it will provide better compatibility and matching by analyzing your genetic predisposition to the other people on the site. While it is free, it is not an optional service so all new users and all existing users will be required to submit their blood sample. While I'm not sure that this will actually help people match up better it seems like this really forces Match.com and other dating sites to up their ante."
