Matthew Shaer:

According to Facebook’s Lev Popov, beginning today, Facebook fans can flag the devices they use to sign onto the site – an Apple iPhone, for instance, or your laptop – and then request a notification when someone logs on to their account using an unapproved device. A similar functionality has long been available on platforms such AIM, but until now, it was absent from Facebook.

Don’t get me wrong this is a great move, but it is not what people are really concerned about. We want to control our privacy.
