The Twitter app for Facebook—the little app that pulls tweets into your Facebook profile—just got way more useful. It shows all of your Facebook friends who are on Twitter, so it's way easier to follow 'em. Updated.
Update: The original Twitter announcement has been updated to show that there's something wonky going on with this new feature right now:
The Facebook app cannot currently access your Facebook friend list. We believe this is an issue on Facebook's end.
Looks like we'll have to wait a bit before easily stalking our Facebook friends.
Update 2: Facebook is being kind of a dick! Twitter says:
Facebook has notified us that they have blocked the update to our application, and we are working on a resolution with them.
