Argument: Wikipedia is generally unreliable
Nicholas Carr, "The amorality of Web 2.0", Rough Type: Nicholas Carr's Blog (3 Oct. 2005) - "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."
