I'm guessing that in practice means ranking websites by the popularity of their delusions. The problem is that you can't distinguish facts from fictions without reference to the external world. Furthermore, given how bad wikipedia is at getting its "facts" wright about any vaguely controversial topic, I don't have a lot of confidence in the ability of the internet to settle on the truth.

Edit: speaking of bad sources of "facts", why are you treating New Scientist as a reasonable source?
