Facebook To Share Ads Based On Location History With Advertisers
 

I know people want to make a big deal out of this, but this is hardly shocking (this is Facebook after all). Our recommendation about anything Facebook related? Don't like it, don't use it. With Nearby Friends, your location history is private to you and only you -- until the social network decides otherwise. Surprised? Don't be. Facebook is in the advertising business.
