I am judging Wikipedia’s entry for the Center for Nutrition Policy and Promotion (http://en.wikipedia.org/wiki/Center_for_Nutrition_Policy_and_Promotion) based on its quality and transparency.

All of the hundreds of contributors to this page were listed with their contributions.  I found that I could email many of them if I wanted to.  For those who had profiles, I could read about who they were and what other articles they worked on.  I could even compair any two different versions of the page.  The page has been around since 2005, so it has had a very long reveiw process and has been heavily edited.  It was last updated on April 12, 2012, meaning that its content is most likely up to date.  Government websites and pdf documents cited in the article were available at the bottom of the page, and links within the article are all functional.  I feel comfortable that I know where the information on this page came from.
