I enjoy both. Twitter more for keeping up with things; facebook for keeping up with people. Most of my father's side of the family is on facebook, so if I want to find out who is getting married or died or is sick (or in the case of one of my cousins, whose house burned down and lost her husband), I will click over to facebook. It's a slower pace than twitter and you can keep up with loved ones easier. If I want to see the latest in news or entertainment, then I will go to twitter. I haven't really seen it do much else.
