I've been on a few Facebook vacations, and I've always been disappointed to see how many people use it as their sole means of keeping in touch with friends (meaning, I don't exist if I'm not on FB with them). You won't get emails from some of these people, even if you write to them. It's as if they either aren't checking, or can't be bothered to write more than a few lines anymore.
