Privacy Theater
I have a piece in today’s NY Times “Room for Debate” feature, on whether the government should regulate Facebook.

Another Privacy Misstep from Facebook
Facebook is once again clashing with its users over privacy. As a user myself, I was pretty unhappy about the recently changed privacy control.
