If you haven't learned to double-check your Wikipedia.com research yet, now would be the most entertaining time to do it.  Thanks to the advent of the Wikipedia Scanner, built by CalTech grad student Virgil Griffith, anyone can find the identity of the people who edit and input information on each entry.  Several governmental, corporate and media employees have been revealed as deleting unfavorable information since its release. One of the more humorous examples of editing was traced to someone at The New York Times who inserted "jerk, jerk, jerk" repeatedly into the article on George W. Bush. In another case, a CIA agent edited the lyrics to a song that appeared on Buffy the Vampire Slayer.  WIRED magazine's article takes a more in-depth look at the Wikipedia Scanner.
