You might be onto something... There are so many different sites out there, there is Match.com the most well know, but there is dating for people over 50, JDate for Jewish people, eHarmony.com too lengthy psych assessment, people who love horses, cowboys and cowgirls, nerds and geeks, 20-something's, GLBT, goth, Christians.com, dating skiers, wine lovers, lawyers, chefs, travel lovers, and so many more. Then there is all the international ones in almost every country.

I bet you if you, or the collective we, could put together a solid unique proposal, Match.com would read it. If you are serious, I would love to work on something like this. PM or post on here.
