A new Facebook app tracks your taken crushes and then e-mails you when they break up.
If you're on the social networking monster Facebook, it's very likely you've used the site to seek out an old flame or benignly stalk a new crush at least once. Yet very few of the site's applications acknowledge that reality, leaving people to think that maybe they're the only ones searching for their high school girlfriends in the middle of the night. Enter web developer Dan Loewenherz and his newest invention, Breakup Notifier.
Capitalizing on the tendency of internet users to keep an eye on potential mates via their Facebook profiles, Breakup Notifier lets you anonymously identify Facebook friends who are taken and then e-mails you if ever that person's relationship status changes. It's a simple and effective—if not slightly creepy—way to ramp up your love life.
