I haven't tried anything, but have you or are you planning to try searching for "facebook dating" in clickbank marketplace, the demographic could be men with single/divorced status, there is one product (vendor name: dlamont) with a quick search, but there could be more for girls too. I have no idea in fact, but perhaps something staying in the facebook domain could perform well, not sure.
i promoted facebook games guides. it is fine. but sometimes not good And everytime suckz with other products.
