Ah! Of course you mean Wikipedia. I know the one. Yes, unbiased. Hmmmn not quite sure about that one Alexander. That's as naive as saying that if it's on the television it must be true.
In fact much of, say, the climate change write ups can be attributed to one particular individual who goes by the name of William Collolley.
An interesting character who is known to edit thousands of posts over the years substituting fact for his opinion. Anyone can do it. Just go to the site and pick any subject and it's there for you to change as you wish. Do be careful not to change anything which might lead to legal action by libel or other such deeds.
Perhaps you might read this piece about him which gives a concise summation of where Wikipedia is really at:

You must admit that it will make you think twice about using Wiki as a source of fact next time.
