Launched well ahead of schedule and ahead of the iCloud's release, Apple's new 'Find My Friends' app does precisely what its name implies: identify the exact GPS co-ordinates of your closest friends and relatives.
Whereas prior GPS applications would either broadcast your location as scheduled updates or whenever you renewed your Facebook status, the 'Find My Friends' app perpetually announces your current co-ordinates as you go about your business. For added privacy, users can select chunks of time to go off the grid -- during Happy Hour, for instance, you wouldn't want your professor discovering you're at the local bar instead of in a class tutorial. Personally, I place a degree of value on chance and serendipity, though it would be foolish to ignore the utility of this application. Finally, having the infamous "Where you at?" conversation will be a thing of the past.
