Coincidence? Nope. Pandora pulled my musical preferences from my public Facebook profile. I didn't ask it to. It just did. It was both cool and just the tiniest bit creepy.
At the time, they were just “discussing” implementing these changes. Guess we’re done talking about it.
As usual with Facebook, you’re already entered into their nefarious scheme by default, though you can opt out. But it’s not exactly a cakewalk. PC World’s JR Raphael details the multistep tango for turning off auto-sharing and disentangling your data from third-party sites.
Zuckerberg talks about the convenience of the Social Graph, and he’s right -- it is more convenient when Pandora knows more about my musical preferences. (Of course, considering a premium Pandora account costs $36 a year, it should already know plenty.) It’s more convenient to simply click a button on a site I’ve just discovered and populate yet another Web profile with information I’ve already entered into Facebook. It’s more convenient to see which friends share my perverse interests without having to scroll through their Facebook profiles.
But the social graph isn’t about convenience -- it’s about control. Facebook wants to own single-sign-on and authentication, just as Apple wants to own what apps you can install on your Wonder Tablet, and Amazon wants to control how you manage e-books on your Kindle -- only Facebooks wants to do it across the entire Web.
