Facebook is rolling forward with Graph Search which makes it easier than before to find people, pages, pictures, and more. Are you concerned with your privacy on today's evolving social network practices?
No, because I don't post anything there that I wouldn't say or show in front of almost anyone. My FB friend list is fairly small, but I wouldn't care *myself* if stuff leaked farther. It's always been a pain that you couldn't search on FB.
It's a social network. What you post isn't suppose to be completely private and that's the first thing I tell anyone new to them. What you post can and will be found by someone dedicated enough to look it up.
