If you're like me and watch the Colbert Report religiously, you would have seen last night's show where Stephen Colbert talked about Wikipedia in 'The Word' portion of show. In the segment, he educated the audience about Wikipedia- how you can log in and add "facts" or as he called it "Wikiality". To show how it works, he went online to change some facts about George Washington owning slaves and elephants population growth. Funny thing is- he actually did this. And now Wikipedia has blocked him from the site. The story is here.
Here is the video from the show.
