When I worked at The Washington Post we were among the first group of companies to integrate the then new Social Graph. I immediately deleted my Facebook account.

I was appalled when I saw that we could identify, not only visitor's names, but their friends, access public photos, and all of their profile information. All of this without any action on the user's part and before there were any privacy controls.

This is just the next logical step-federating data collection across multiple sites, not just FB.

I'm obviously in the minority since FB has grown tremendously in the past 2 years but I've not looked back. I dread the forthcoming lack of privacy and anonymity our world is heading toward.
