There's a really interesting article by John Timmer from Ars Technica about a Wikipedia hoax that fooled the likes of The Guardian. Apparently, an Irish college student inserted some finely crafted, yet totally false wording into the Wikipedia entry for composer Maurice Jarre, who had just passed. That finely crafted, yet totally false wording was directly lifted by several news organizations who wrote about Jarre's life. OOPS! Fool me once, shame on you. Fool me twice, umm...Wikipedia, umm...won't get fooled again.
