Another problem that the author neglects to mention is that Meetro didn't really seem to solve any specific problem. Foursquare is so successful for two reasons. It's a game, so people want to check in and leave their mark (solving the persistence problem he mentions). They're solving a problem by providing entertainment. I'm not seeing this as much in Meetro. Second, everybody has smart phones now. Foursquare succeeds where Dodgeball fails because anybody can participate, with almost no effort.
