I have been hooked on Facebook before. I sometimes still am, but one of the things I have come to discover is that I don't like having Facebook friends that I am not friends with in real life, even if I know you it does not mean that we are friends and just because we are "Facebook Friends" also doesn't mean that I am your friend. Unfortunately people do not think the same as me and seem to be upset when i delete them on Facebook even if we haven't spoken in over a year. As I delete people i tend to get "delete happy" and have now developed a system which allows me to keep or delete.
