An amazing little app called Foursquare brings a city to life. Subscribers are able to interact not only with other users but with the very city itself and that is what social media is. User feedback about places and events drives this application. Tied into a GPS system, as well as a fun game, this app has it all.

Either in town or far from home this app lets you know the wherever you are like the back of your hand. You will be a local just from checking out some of the comments of the cities inhabitants. It can even steer you away from that sushi place that gives everyone heartburn.

It’s a great tool if you are trying to impress a client or even a date. With a quick glance you can know which restaurant offers the best selection for lunch or even who is having a great sale on dinner for two. It really opens up a lot of new avenues to explore – literally.

The game that is tied into the app is an achievement system that offers real life rewards. For accomplishing certain criteria you can earn badges. If you frequent an establishment enough you can even be awarded the title mayor of that location.

There is so much in Foursquare that there would be zero reason not to sign up. Shops that are in the know often offer specials to Foursquare users exclusively. It is not unheard of to mention that you are the mayor of that location and receive a free meal or coffee. If your favorite places are not familiar with the program then let them know. Foursquare boasts one of the largest subscriber networks for a social location system.

It also has a great tie into Twitter. The graphics aren’t that hot but they really listen to their users. If a bug turns up they are usually jump on the problem quickly.

If you are a business owner then Foursquare really offers some excellent opportunities to bring in new customers and retaining loyal customers. They even offer promotional materials on their website. There are just a lot of interesting ways to incorporate Foursquare and what social media is into your advertising plan.
