FACEBOOK'S TRACKING is rather powerful because merely logging out of Facebook still results in Facebook logging my clickstream.
Facebook's tracking button identifies people by IP address. I am trying to prevent that from happening so I've appended the line "127.0.0.1 facebook.com" in my /etc/hosts file. This should block Facebook's tracking of me on other sites but it also can disable Facebook Connect. I'm playing with the result and feel like I've restored a level of my online privacy.
