I’m not sure when foursquare added Louisville. I just noticed it a couple of weeks ago. I started seeing tweets with foursquare updates from the locals.
If you’re not familiar with foursquare it’s sort of like Loopt or Brightkite. Using your phone, you “check-in” when you visit a business and your location is pushed out to your foursquare friends, and Twitter and Facebook if you choose. What’s different about foursquare is the game aspect. Each time you check-in you get points and if you check-in enough at one location you become the Mayor. I’m currently the Mayor of Kroger, which is a sad reflection of my social life.
There are a couple of interesting features of foursquare that every small business should be aware of. When you pull up the check-in screen there’s a link to your business listing on Yelp. One more reason why you should claim your business listing on Yelp. More and more traffic is being driven to this review site. There’s also a Tip section for each listing where users can leave suggestions or comments about your business.
If you’re a business owner stop what you’re doing and make sure you have a listing on foursquare. It’s easy. Just follow this link and fill out the form: http://foursquare.com/add_venue. While you’re at it why not claim your business listing at Yelp (http://www.yelp.com/business), Google (http://www.google.com/lbc/) and Bing (https://ssl.bing.com/listings/ListingCenter.aspx).
By the way, here’s my page on foursquare if you want to become friends. http://foursquare.com/user/davesharpe
Update: According to this Mashable article, you can now update your location from anywhere, not just the cities on foursquare’s list.
