When you first sign up, Foursquare locates you and looks for places you can check into. Each check in gives you points which, if collected enough, make you the mayor of that place. As if you were a boyscout you can unlock badges visiting the same place frequently (the gym would be a great idea).
"Places" means usually bars and shops, but they are also bus stops, the nearest park or the farthest romantic spot. There are places that offer special prizes and discounts if you can show that you are Mayor of that place. The list of associated places is growing every day and players can add more to the overall list.
You can leave comments for those who came to that place in the future, so Foursquare can be a very powerful social tool for local shops and starting business.
Foursquare was born to become much more than a social geocatching game. It will achieve its goal when the number of associated places is really significant. Meanwhile, it's fun to play competing against friends and neighbors just strolling around home.
