I must admit that I also though it was a Facebook app at first, since that's where I've been seeing all the updates from people.

I can see fun of it, too: the competition to become Mayor, getting treats from places you frequent anyway. But I still find the idea of a game that tracks my movements, however voluntarily, a little unnerving. Especially when you hook it in with a Facebook app, which potentially gives it access to lots of personal information.
