I use facebook. I agree with the people on the news that how can you have 1000 friends that you know really well. I have all the privacy settings set so that only my friends can see my information. I only allow those to be friends with me if I really know them well. Also the 2 questions that the news caster said are a real reminder to what should we post on our sites. I think about what I'm going to post a number of times before I post it. If it doesn't seem right I don't post it. Just think before you post would.
