Foursquare crossed another milestone recently by clocking a 10 Million user base, and have released an infographic that tracks the growth of FS since its inception. On the iPhone app, they eliminated some friction from the check-in process, by adding a new check-in button at the screen footer, enabling users to check-in without going through places as before.
