I remember Amit Singhal's post after the Panda fiasco on what constitutes a "good" website. He was, consciously or not, describing Wikipedia.
Now you know why Wikipedia ranks so highly, it touches on every related aspect to your search terms.
A few years ago, Microsoft made a very bad mistake with its search engine in believing all that academic crap about the Semantic Web. The reality is that the Semantic Web is a great idea but the real world just doesn't use it. I wonder if Google has made a similar error?
