Note to the New York Times: Don’t use Wikipedia as an authoritative source. Lifting text verbatim from Wikipedia would seem to be a poor practice as well.
Without taking a huge digression, the advantage of a Wiki is supposedly that a "community" of folks shares their knowledge to build an informative web site with an easy to use authoring tool. There's a problem though, if some of the community have more enthusiasm than knowledge. Or more bias.
UPDATE: Apparently the copying was in the other direction.
