San Francisco mayor Gavin Newsom made a gaffe today during his TechCrunch talk, listing New York’s Foursquare as an example of an SF-based start-up in the course of explaining why his city is the best place on earth for start-ups. This is basically the same as someone claiming Biggie Smalls and Jay-Z grew up in Los Angeles. Hands off our prized location-based check-in service, dude!
