While most social network talk these days is dominated by Facebook and Twitter, the growth rate for Foursquare is notably increasing. The location-based social media site has recently received its 40 millionth checkin, meaning that it has doubled its total number of checkins in a little over a month and recently acquired over one million users.

The growth has no doubt been fueled by the hype surrounding the service and the rumors of a buyout. With Facebook set to integrate location-based features of its own, the site’s growth may be hampered if Facebook doesn’t integrate with the third-party service.
