The Wheretheladies.at web app that tracks female Foursquare checkins is available for the iPhone now, folks. Just one flick of a nerdy smartphone app, and users are effortlessly guided towards the largest critical mass of ladies out for a night on the town. As TechCrunch puts it this is "essentially nerds using technology to circumvent Darwinism" and lucky for us, it's available only in San Francisco for now. Now the only question is, who's willing to geek out this hard to find the ladies? Gents, would you use it? Gals, thoughts?
