Ok, maybe you're a paranoid person who doesn't like everyone knows where you're at. Or perhaps you affraid that one of your friends is a stalker, then you don't have to worry. Because according to uLocate, Buddy Beacon only gets updated when you set your location (pheew..).
Here's a short list of what you can do with Buddy Beacon:
Update your status and share your location
‘Nudge’ your buddies to get them to update their location and status
Grow your network and invite new buddies with Facebook
Show the locations of your buddies on a map
Yup, that's right. If Twitter is not enough to tell your friends at Facebook what're you doing every minutes, now you can add your location as well. To get Buddy Beacon, just point your Safari to this link. Sources are from Apple, via MacWorld.
