Foursquare Begins Testing An “Add To Foursquare” Button With WSJ

One surefire way to know that a service is doing well is when you see their buttons start appearing all over the web. We've seen it with Facebook , we've seen it with Twitter ( Tweetmeme buttons ), and now we're going to start seeing it with Foursquare . To be clear, the "Add to Foursquare" buttons aren't designed to be as ubiquitous as some of the other sharing buttons around the web. Instead, this button allows content providers to give readers one-click access to add venues to their Foursquare to-do list. The first such partner that is testing this out is the Wall Street Journal. Beginning tomorrow, the newspaper's site will feature these buttons next to venues featured in articles (specifically, in restaurant reviews and other cultural coverage).
