Facebook is not my favourite company. I can just about believe that MZ and his peers want to share everything with everyone all the time, I cannot believe (if he really is this smart) that he believes everyone else does too. Facebook privacy controls are baroque and complicated and change arbitrarily and frequently - if he really is that clever and he really does want to give us the option not to share publically, why does he make it so damn difficult? He's on record as saying that if he did it all again he'd rather have made the default public, plus his advertisers would obviously far rather everything was public - he really is being disingenuous, and rather obviously so
