Foursquare is a location-based game. From Foursquare’s website: “We’re all about helping you find new ways to explore the city. We’ll help you meet up with your friends and let you earn points and unlock badges for discovering new places, doing new things and meeting new people.”

Basically, Foursquare works like last.fm or librarything, but instead of sharing music you’ve listened to or books you’ve read, you’re sharing places you’re visiting, and aggregating that list out to your friends.

To play, install an app on your phone, via an iPhone or Android app (a Blackberry one is in the works). You can also use the mobile version of their website for other phones that have web access. Then go visit places … like a coffee shop, a restaurant … basically wherever it is that you go. Once there, “check in” with the app. Checking in gives you points and badges. If you visit a place more than anyone else, you become the “mayor” of that place (until your title is swiped by someone else).

Friend people, and see your points tallied with everyone on your friends list. In the process, you can also create to-do lists and tips at each place you visit, and suggest things for your friends to try or do. Every time you do something, it can be shared with your Twitter and Facebook friends.

So … how does this relate to libraries again?

Well… here are some ideas for your library or organization on Foursquare:

1. Add your library as a place, or edit the entry if someone else has already added it. You can enter your street address (Google map is included, phone number, and your library’s Twitter name.
2. Add tags relevant to the library. For example, I have added the tags library, books, music, movies, and wifi to my library’s Foursquare entry. If you are in the area (Foursquare is a location-based service, so it knows where you are) and search for wifi – guess who’s at the top of the list? Yep – the library.
3. Add Tips and To Do lists. When you check in to a place, you have the option to add tips of things you can do there, and you can create To-Do lists of things you want to do there. For libraries, both are helpful – it’s a way to broadcast your services to Foursquare players. To Do lists are handy, because you can make the list and other players can add those To Do list items to their lists, too. When they do something on those lists, they gain points. Think of it as a fun way to get people doing stuff at your library! Just think – someone could gain points by getting a library card – how cool is that?
4. Add your big events. Then, you can have an event check-in with prizes for the first person who checks in, etc.
5. Shout outs. These are a type of status update, and can be sent to Twitter and Facebook. So do stuff, then shout out that you’ve done them.

Ok – so Foursquare is definitely fadish right now, and is mainly played by Twitter and Facebook users. But it’s also a great way to connect with a very active, involved online mobile community – and pretty much every city and town has that these days.
