In addition to the questions raised about Wikipedia...

Google does not produce the most reliable sources first and then list downward by reliability.

It lists whatever the most popular searches are first. Then lists down by popularity.

If you type into Google "Moon Hoax" your first Several Pages will be nothing but HB sites.

If you type in any question about Evolution, Big Bang or creationism, you may as well skip the first page because it will all be creationist websites.

Does this have much to do with the many misconceptions floating around?
