Is it time to leave facebook?

This article on the ZDNet Tech Broiler provides a very cautionary tale for FaceBookers, adding to the uproar from many tech pundits about the privacy issues for regular users of Facebook.

I have already used the personal settings "opt out" on Facebook to reduce my exposure, but after reading the linked article I am not so sure I have protected myself adequately.

My grandkids, who are avid FaceBookers probably don't care about their privacy right now, but their FB content may come back to haunt them in the future.
