With the recent influx of actual locations offering deals for mayors, such as free or 
reduced drinks/appetizers/admission, Foursquare is gaining a purpose. When Will I Be Mayor uses the public Foursquare API to help get you that coveted mayorship.
After you create an account, it prompts you to allow them to authorize them using the Foursquare API and read your stream of checkins. From there, it will tell you how many checkins you have at a location, who the mayor is and how many more you should need to steal the title.
You can even search for a particular site if you have your eyes on being mayor there or if they are running an upcoming special. All thanks to When Will I Be Mayor. It was interesting to see how far behind I was in certain spots and how far ahead in others. So using it in reverse let’s you know who is creeping up behind you as well.
I have written recently about how Foursquare has failed me, and this does not detract or add to that. It is just a good implementation of the API to show how mayorships works inside the game known as Foursquare.
