PostPoints tip: Facebook is only for friends

Tracking Facebook's latest privacy moves can be a full-time job--with a high risk of having to run a correction because one aspect or another of its latest features and options was less clear than initially advertised. But two guidelines about that social-networking site still hold true if you want to protect your privacy: Limit your Facebook friends to your real friends, and then limit your data's visibility to them alone. The first should be obvious, but many Facebook users seem to forget that and indiscriminately accept friend requests from people with whom they don't share any prior level of trust. (So if we haven't actually met, please don't feel bad if I don't accept your friend request.) The second step can sometimes be thwarted by Facebook's shifting standards, but at least it's somewhat easy to remember to set every available data-visibility menu on your privacy-settings pages to "Only Friends."
