Facebook's "export tool" generates an incomplete static HTML version of some of the data you put into Facebook. The friend list wouldn't really be of any use unless people had unique names.

Go to your google account settings, and there is an option called "Connected accounts". Facebook is listed there. I don't know what this actually does however.

That just gives the Googmonster access to your other social accounts data, so that it can "enhance" your search experience.
