With each new change Facebook makes, users' privacy becomes a little less ... nonexistent, if you will. The most recent "News Feed" modifications, for example, display everything you say and do on the site to all of your "friends," and even to the public. And now, even after logging out of Facebook, permanent "cookies" track all your movements on websites that contain Facebook buttons or widgets.
"Even if you are logged out, Facebook still knows and can track every page you visit," Cubrilovic wrote on a recent blog posting. "The only solution is to delete every Facebook cookie in your browser, or to use a separate browser for Facebook interactions" (http://nikcub-static.appspot.com/lo...).
Facebook, of course, has become infamous for simply changing its site setup, including privacy settings, and leaving it up to users to figure out how to contain their breached information after the fact. It has switched from an "opt-in" approach, where users used to be given the option to "upgrade" to new features, to a much more complicated "opt-out" approach, where Facebook makes drastic changes and leaves it up to users to somehow figure out how to change things back to the way they were (if such an option is even still possible).
