I do. I have 42 "friends" on there. Most of them are atheists. Some family friends, one ex, one rude "friend," one who never posts but one meme every 2 months, etc... Facebook seems more of a hassle to me. I only keep it to read athesits' articles and science articles. Along with the local news.
My Messenger is always dry. One friend talks for 3 minutes once a week, (the too truthful one) I have my ignorant ex on there, (nothing intelligent to talk about with him that he would understand), a friend whom is in the Air Force and works nights, (hardly a conversation there), one mom friend working 3 jobs and has no time to talk, a Christian friend whom never checks or answers messages, and my bosses. So you see why I am on here more and don't really have friends? I would love to get rid of both, but my bosses need to get ahold of me. So, I just quit Facebook after my innocent post got trashed.
