Pleeker - the higher priority for not for profit sites, governments and institutions/organisations came from a very long thread off WebProWorld. Twas 3/4 months back. I remember taking a look at the G page they referenced and reading about how G gives more credence to such sites over commercial sites - it said nothing about by how much. Now that you ask I wish I had bookmarked the exact thread.
Wasn't aware Googleguy said that all pages are equal in the eyes of the G algo.
Good points Flicker and yintercept.
