More people use Wikipedia than Amazon or eBay–in fact it’s up there in the top-ten Alexa rankings with those moneyed funhouses MySpace, Facebook, and YouTube. Why? Because it has 2.2 million articles, and because it’s very often the first hit in a Google search, and because it just feels good to find something there–even, or especially, when the article you find is maybe a little clumsily written.
