Remember all those FaceBook Apps that would spam users or trick you into spamming your friends when you downloaded them? FaceBook cracked down on them long ago, pretty much puttting a stop to the egregious behaviors that were messing with the user experience. Of course, some application developers have sought to work around the new policies and FaceBook has had to continue to nuance the guidelines and to continue to tweak enforcement. Overall, they do a good job at letting users share the apps they like and prevent abuse by those who go overboard. The back and forth, the debate on the FaceBook Developers Forum, feedback from users and FaceBook reaction have been a wonderful real-time public playing out of self-regulation in action. As always, Inside FaceBook, provides great coverage of the action.
