"Then Facebook decided to turn “your” profile page into your identity online — figuring, rightly, that there’s money and power in being the place where people define themselves. But to do that, the folks at Facebook had to make sure that the information you give it was public.
So in December, with the help of newly hired Beltway privacy experts, it reneged on its privacy promises and made much of your profile information public by default. That includes the city that you live in, your name, your photo, the names of your friends and the causes you’ve signed onto.
This spring Facebook took that even further. All the items you list as things you like must become public and linked to public profile pages. If you don’t want them linked and made public, then you don’t get them — though Facebook nicely hangs onto them in its database in order to let advertisers target you.
This includes your music preferences, employment information, reading preferences, schools, etc. All the things that make up your profile. They all must be public — and linked to public pages for each of those bits of info — or you don’t get them at all. That’s hardly a choice, and the whole system is maddeningly complex.
Simultaneously, the company began shipping your profile information off pre-emptively to Yelp, Pandora and Microsoft — so that if you show up there while already logged into Facebook, the sites can “personalize” your experience when you show up. You can try to opt out after the fact, but you’ll need a master’s in Facebook bureaucracy to stop it permanently."
