I have never had any of my privacy settings changed by an update to facebook, Dave. The privacy settings are very easy to set and it doesn't take any time to check them or be a computer expert to do it..

Your story about the soldiers doesn't have as much to do with facebook as the soldiers being idiots for posting pictures on the Internet which show something that they aren't suppose to show in the first place, that's an Internet thing not a facebook thing.

While on the subject of privacy I wonder how many here on the forums haven't turned the gps settings off on their cell phone and their cameras.. With very little effort people can get your exact location here on earth with the information that is know stored digitally with their images..
