Foursquare is a web app that lets you keep track of where you go, get ideas and reviews from restaurants, merchants and public places, keep tabs on your friends, and compete to be "Mayor" of local attractions. It does a lot, yet is very simple to use and available on GPS-enabled smartphones. All you need to do is download the app.
Mashable has a couple of articles that will let you know more about Foursquare. It's official, Foursquare Surpasses 5 Million Users and How 5 Brands Are Mastering the Game of Foursquare.
So whenever you come to the library, remember to "check-in" on Foursquare before you check-out a book or DVD ;^P
Congrats to Megan G. who is the current Mayor of the library on Foursquare as of this writing, but you too can try to become the Mayor of Homewood Public Library! C-ya!
