Tech nerds and fashion folks can bridge the rather great divide between the two groups if Nerd Merit Badges have their way. The company makes proper badges (think military, leather men, police, girl scouts) for the geeks obsessed with mobile device app Foursquare. Foursquare allows you to check in via mobile phone anywhere: restaurants, clubs, PATH Train stations. The more you check in, the more badges you earn. You can also become the mayor of any given place. That, too, has a badge.
