Apparently Facebook has started letting other websites access user information (surprise, surprise!) to third parties. They call it the "Facebook Development Platform."

To restrict use of your information, do the following:
Click "Privacy" on top right.
Under the "Facebook Platform" section click"Edit Settings".
Scroll down to the bottom and UNCHECK ALL of the items under facebook platform.

Most creepy is the inclusion of photographs!
