I find it to be mostly an annoyance... people sending me virtual beers, and offers to send one to someone else; offers to join vampire clubs; invitations to join some movement to save whatever; etc.. But, I keep my account because every once in a while an old long lost friend pops up there. Like CJ, I have had a couple of people from high school contact me, and I don't remember who they are. Pretty awkward. I'm too much of a coward to just tell them that I don't know who the fuck they are (pretty much an admission that I was doing too many drugs in high school)... I just write some generic stuff: hey, how have you been? what are you up to these days?
