A start-up company called Motivity developed this application for Foursquare. Ratio Finder lets users find check-in locations with the sharpest gender imbalances so that they can go there and, well, presumably flirt and such. Mickey Kaus writes:
A site called Ratio Finder uses GPS data from Foursquare check-ins to generate a map showing which restaurants have more men in them and which have more women in them. Combine this with the information on Facebook, Grindr, and Google, and soon you'll be able to pick your restaurant by flipping through naked pictures of everyone eating there. Or that's the direction we seem to be headed.
