I think a key difference between FB and MySpace is that FB has my parents, pretty much all my relatives, and all of my friends. MySpace had early internet adopters, which were maybe less than 5-10% of my friends? For me, it is MUCH harder to leave FB now than it was to forget MySpace ever existed. I realize though, that some of the HN crowd is completely uninterested in communication through FB, which is ok. HN is really the only place where I have seen people say they have left FB 100% and have no regrets about it. I have to bet that the rest of the world that is already invested on FB will find it much harder to abandon people whose main line of communication is through FB. If I leave FB, I lose touch with good friends that live far from me (and therefore I do not see often IRL), and vast majority of my family's activities (and them getting fat, telling a joke, expressing a stupid opinion, and so on).
