To answer your first question: deep integration. [Hypothetically,] now you can go to someone's facebook page, see your wall-to-wall, message history, and text history. It makes your entire social history easily accessible by unifying the data. To answer your second question, most people don't care about privacy as much as geeks do. In fact, most people don't care about privacy at all. Though it's tempting to say, "they're all just morons and they'll see soon enough," it's probably also partially the case that we (as geeks) are a little paranoid ourselves. At least that's what comes to mine when I hit someone's home page and see a PGP public key. Disclaimer: I will eventually be employed there, but it's not like I have any sort of a clue as to whether this is real or not.
