Of course in David Brin's novel Earth (published in 1990 believe it or not), he shows a world we seem to rapidly be approaching - where privacy and secrecy are considered to be somewhat evil. Looking at the growth of Facebook and other sites where stuff that 20 years ago no one would want you to know about them is now considered great material for your "Wall", I have to wonder if the solution to the privacy problem will turn out to be no one caring? If you look at it, a lot of the privacy issue comes down to asynchronous knowledge - i.e. what you know about me that I don't know about you. If we make sure we can know virtually everything about everyone, is privacy still a problem?
