Facebook
is a personal vault that can contain photos of your firstborn, plans to
bring down your government and, occasionally, a record of your
indiscretions.
Facebook insists it is up to you to decide how much you want others to
see. And that is true, to some extent. But you cannot entirely opt out
of Facebook searches. Facebook, however, does let you fine-tune who can
see your “likes” and pictures, and, to a lesser extent, how much of
yourself to expose to marketers.
The latest of its frequent changes to the site’s privacy settings was
made in December. Facebook is nudging each of its billion subscribers to
review them.
