I use fb daily, mostly to communicate with my friends and family via messenger. Without that feature, I would have been gone a long time ago. As far as privacy goes, they have nothing from me that is any secret, except my birthdate, and I have the strongest privacy settings in place so I hope that would not be an issue. While fb has been fun and enjoyable at times, it is also home to some of the most stupid and hateful people on the planet. I guess you gotta take the bad with the good, or simply don't take it at all!
