Thoughts about FB privacy

I have had FaceBook for 4 or 5 years now and I didn't realize a lot of the changing and things they do to the privacy policy. I don't think that it is very right for them to change it all the time because nobody wants to read the to policy every time they change it (or is that their point?) In the past I have messed with my privacy settings but probably not as much as I need to. I use to use FaceBook all the time but I have slowed way down... Now that I have watched the video about their policy I think I might just delete it... there is no sense in it anymore really...
