Checking In With Foursquare, SMB Style

We're not just checking in to hotels anymore. In fact, now, no matter where you are, you can "check in" and let your friends know what you're up to. Foursquare describes itself as the "app that helps you and your friends make the most of where you are," and is used by 30 million people worldwide - amounting to millions upon millions of "check ins" each and every day.
