Not me. I don't see why it's a big deal, sorry if you get "addicted" to it and are on it for hours. I'm on it maybe an hour most throughout the whole day, just seeing what's up with other people. I found a lot of friends from middle/jr high school, since I really only had friends there, I made like 5 the whole time at highschool, so it was nice to see how everyone looked grown up more and what they were doing.
Also, unless you don't have a privacy setting or friend every person who sends you a friend request, they can't see your info, and it's not like you have to put any of your info up anyway.
