I think you nailed it perfectly, I think Foursquare is being used mostly as a game. It's fun, and addicting, but it's a "game" it's a "social game", but what it is not is a tie in with all my friends like Facebook, nor a restaurant guide like Yelp. Which is a good thing, as long as Foursquare can recognize how it is being used, and how to capitalize on it before they go belly up. And if it does, oh well, didn't the founders already make $100mil selling their first location based company to Google?
