Fans of Foursquare and Facebook will now be getting a little extra integration between the two. The Foursquare team has just tweeted that Foursquare check-ins will now appear as pins on the Facebook Timeline map as long as they've been shared to Facebook.

This also appears to work retroactively, so anything you've already shared should show up now as well. There are already so many different check-in services to manage that it's nice to see Foursquare making sharing with Facebook more streamlined.
