Tellingly, a "Break-up Notifier" app recently attracted over 100,000 Facebook users less than 24 hours after its debut. The new app lets users pick "friends" whose Facebook relationship status they'd
like to monitor. "When that status changes, the stalker ... er -- user, is notified via email,"
The New York Daily News explains. Insisting
that he only created the "Break-up Notifier" as a joke, the app's creator, Dan Loewenherz, tells The News: "I wasn't even sure if it was work at first." That is has taken shouldn't come as a surprise
to anyone familiar with Facebook and its common uses. Indeed, most users will admit to at least testing out the "stalking" capabilities of Facebook, which privacy advocates warn has great potential
for evil -- a concern shared by Loewenherz. "I just really hope people use it for good, not evil," he tells The News. That said, "It's really a practical thing," he adds." If you're going to refresh
someone's page 20 times a day, why not have an alert on it?" And why not make a little money off people's compulsions? As such, Loewenherz plans to let users monitor two friends for free, then to
charge $5 to keep tabs on up to seven people using his new service.
