well to answer your first question, I like it because it keeps me in touch with friends. I became less mobile over a year ago, so able to get out and about less, and had it not been for facebook the chances are I'd have lost touch with many. Also, as a result of that mobility issue, I had to sell up and move well away to where I could afford to live, and it does help mekeep in touch with what is happening back home. I have also found new friends, many of whom are on here anyway, but over there I can interact in ways I couldn't here.
