I really wouldn't care that much. In fact, it might actually be good, because it would be a way of sort of forcing people to be a bit more open about themselves. Once everyone opens up and shows how vulnerable and human they are, a lot of the stigmas and fears stop mattering. Everybody has insecurities, everybody has desires, ect. Me and most of my friends are open about the fact that we look at the pronz, and at some point or another, have built up a pronz folder.
And plus, what kind of person would go around snooping through your history and sifting through your computer files? I mean, there's accidents, but I trust that my friends and family wouldn't do that. It's the same as going through someone's mail.
