Wall Street Journal has got a confidential 2008 document about Google's point of view of user's privacy and how to make money with it.
With 2 nice interactive graphics. A must-see.

I know the document is from 2008 and about ad targeting, but could it be the one from which Facebook pretends to know about Google’s social product plans? http://techcrunch.com/2010/08/02/facebook-boasting-they-have-googles-social-strategy-product-documents/

The "Google's Widening Reach" graph reminds you of Facebook's "Evolution of Privacy", doesn't it http://mattmckeon.com/facebook-privacy/?

George R created another thread from this 2008 document (more specifically about the "Wacky Ideas" section): http://blogoscoped.com/forum/173294.html

This is like an argument over what to have for dinner compared to what must have transpired over the current net neutrality agreement with Verizon, where wireless is pretty much exempted from net neutrality requirements.
