"Followed quickly by: 'I don't have to; my less-savvy friends would. And I'm in their graph.'" That's actually a very good point. I'm not too worried about the stuff I write about on my own Facebook wall -- I know it's set to private, I don't rant, put offensive material, etc. What scares me is what other people write about me on their own walls with God-know-what-kind of privacy setting, the pictures that they tag of me, etc. Even if everything is set "Fort Knox" mode, you're still just one Facebook bug/vulnerability away from it all being revealed. There was a BlackHat talk this summer called "Faces of Facebook" by Dr. Alessandro Acquisti [1] where he extracts a person's SSN just from an image of their face (by cross referencing Facebook and other things). Scary stuff. [1] http://www.heinz.cmu.edu/~acquisti/face-recognition-study-FAQ/acquisti-faces-BLACKHAT-draft.pdf http://www.heinz.cmu.edu/~acquisti/face-recognition-study-FA... (PDF)

After so many privacy setting changes, I see no reason why the guideline would now be anything but: don't put anything on Facebook you wouldn't want being made public anymore. I mean, I have stuff on my Facebook that I'd rather keep to my group of friends, but nothing on there that absolutely has to remain within that group anymore.

  After so many privacy setting changes, I see no reason why the guideline would now be anything but: don't put anything on Facebook you wouldn't want being made public anymore. The previous two commenters' point is that this doesn't help you. You have to worry about what other people post about you.
