Facebook is ramping up it's efforts once again to break down the walls of ANY privacy between users with it's biggest Big Brother step yet.

This week the worlds biggest social network revealed the new "Nearby Friends" feature where anyone can locate a friends' cell phone via GPS to detail the history of EXACTLY where that person was and is at any given time.

You can continuously track them as they move . . . and you can even get alerts when you have friends nearby.

Fortunately it's not a feature that you are required to use this time around. You have the luxury of being able to OPT-IN.

Keep your eyes open for the new "Nearby Friends" to be rolling out on iPhone and Android in the coming days.
