Thing 7 Stretch

Today I was doing some research in order to upgrade my cell phone. I wanted to get information on the Blackberry. Many links that I chose from search engine results directed me to commercial sites where the Blackberry is actually being sold. I just wanted non-sales information, so I tried wikipedia. The content seemed valid and well written. Because of this exercise, I visited the History and Discussion tabs. I had never done this before although I have used wikipedia quite a lot. I found the History tab info to be quite cumbersome and confusing. The Discussion section provides the reader with a sense of whether or not the info within the article is valid and even gives the article a quality rating based on several criteria. That's pretty strenuous. But what/who gives the source of the quality ratings their expertise? What qualifies them to do the rating?
