Anyone can publish on the internet. There is not editorial board for the internet. Make sure you evalute content you find. Check the source, to insure it is credible. While the internet has lots of sites and lots of information, it does not have everything.
Content is only on the internet is someone put it there.
Just because you get 10,000 hits, doesn't mean you have to look at all of them. Don't let the number of sites returned when you do a search overwhelm you. If you can't find what you are looking for in the first 20 or so sites, you might need to refine or rethink your search terms or accept the fact that the information you are looking for is not on the internet. There is more than one way to find what you are looking for on the internet.
