If you're a casual Facebook member like me, you may find this piece on the social networking site from The Nation illuminating. It certainly made me think twice about what I plan to put on my page. But what I found most interesting was the evolving sense of privacy that the success of Facebook points to:

Growing up online, young people assume their inner circle knows their business. The "new privacy" is about controlling how many people know--not if anyone knows. "Information is not private because no one knows it; it is private because the knowing is limited and controlled," argues Danah Boyd, an anthropologist and social-networking expert at the University of California, Berkeley, who studied the feed controversy for a forthcoming article in the journal Convergence. Facebook's Kelly also contends that privacy is shifting from an "absolute right to be let alone" to an emphasis on control. "We don't think [users are] losing privacy as long as there's a control machine and access restrictions," he said in an interview.
