Sam Altman started Loopt while he was a sophomore at Stanford. In the years since, he has become a champion of the location-based social networking services that are making it harder, day by day, for us to cheat on our significant others. Loopt allows its users to share their location with friends by their phones. The software can also point out restaurants frequented by friends, suggest nearby events and prep the user for a dive in the bushes should an ex come within a 1-mile perimeter. “You are your location,” the one-time Charlie Rose guest wrote recently on All Things Digital. “It’d be easy to learn about me from the neighborhood I live in, the block that I work on, the kinds of restaurants I eat lunch at.” Since his location is in our own Mountain View backyard, we look forward to years of stalking to come.
