This article caught my attention: “In theory, Wikipedia is a beautiful thing - it has to be a beautiful thing if the Web is leading us to a higher consciousness. In reality, though, Wikipedia isn’t very good at all. Certainly, it’s useful - I regularly consult it to get a quick gloss on a subject. But at a factual level it’s unreliable, and the writing is often appalling. I wouldn’t depend on it as a source, and I certainly wouldn’t recommend it to a student writing a research paper.” The counter argument basically states that - to pharse it a bit cynically - the Wikipedia is crap, but it’s free.
