Sadly, while wikipedia is often a good source when combined with other sources, it can't be relied upon to be always factual. It and to a larger degree the "steering" done by Google, have done a lot to lower the internet "IQ" by a considerable amount. Used with caution, though, wikipedia can be useful.
