Privacy: Are you aware of the trade-offs?
The main industry initiative facilitating user privacy is the W3C initiative, Platform for Privacy Preferences (P3P). P3P provides a way for site authors to make their privacy policies available in an automated and structured manner. There's nothing about it that enforces privacy, though. The site's policy may say that they'll sell your name and e-mail address to every pornographer who'll pay for it, and then it's fine for them do that, because you've been warned. Clearly this is not the be-all and end-all of privacy, nor does it claim to be.
