Perhaps you have always liked her, but she has dated the same guy for five years. Wouldn't you want to be the first to know when they break up?
Enter the BreakUp Notifier, a new Facebook application created by Dan Loewenherz, to keep track of crushes as they become single -- and attracted more than 100,000 users in only 24 hours. Loewenherz, a computer programmer based in Beverly Hills, Calif., said he created it mostly as a joke and gave the app to a few friends on Facebook when it suddenly "exploded" overnight.
"I think a lot of people out there think I'm some sort of weirdo Facebook stalker," he told the New York Daily News. "But I made this mostly as a joke and like I said before I'm just blown away how many people are using it."
Loewenherz said that he might start charging for his app soon, so if you want to stalk that special crush -- you might want to download it now for free.
