Needless to say, the site's privacy settings have gotten a wee bit labyrinthine. Recent changes have made virtually all your information public, unless you opt out. But opting out isn't easy—you'll have to click through more than 50 buttons, choosing from more than 170 options. And even if you go through all of that, Facebook will still share info with advertisers unless you find the further opt-outs hidden in the Facebook Ads settings. And even after all of that, community pages will still share your tastes with the world.
