Example: say you want to understand rare earth metals. Look at the Wikipedia entry. 90% of the time, this is probably all people searching for "rare earth metals" read. But now look at this "geology.com" page, or this Nat Geo article. Which would you rather read? Which actually gives you an understanding of the subject?
There needs to be a version of Google that returns the opposite of Wikipedia. I want a page from a specialist site, written by a subject matter expert-- preferably one who knows how to explain things. (Or at least distinguish important information from trivia.)
