The big problem with Facebook stalking is that it takes so much work. Which is why we're so excited for "Breakup Notifier", programmer Dan Loewenherz's new Facebook app for the lazy stalker. Just sign into the app with your Facebook account and choose a group of "taken" friends.
Now, whenever those friends change their relationship statuses, the app will email you-freeing you up for stuff like standing outside peoples' windows, and stealing bits of their hair for your special doll. [Breakup Notifier via Reddit]
