I'm on it, but I have to say I don't use it much, I don't want the whole world to know everything about me. I see people have 90+ friends, but they are not really friends are they?
I also read an article about a guy who decided that for work reasons her wanted to close his accoung, well....the only way he could do it was by going to every place he had ever commented and deleting the posts. It took him forever. You cannot just close your account, be warned.
I have a few friends who live on Facebook, I have a similar issue with this place!!
