Wikipedia has announced that it is testing editor approval of changes to articles. The online encyclopedia says this will facilitate a balance between credibility and openness.
As readers of this blog know, shortly after midnight on June 25, 2007, a Stamford, Connecticut, college student named Matthew Greenberg edited Chris Benoit's Wikipedia page to say that Benoit missed his wrestling appearance the night before because his wife Nancy had died. This was 14 hours before the dead bodies of Chris, Nancy, and Daniel Benoit were discovered by the authorities.
Chapter 9 of my forthcoming book CHRIS & NANCY, entitled "The Wikipedia Hacker," reports in depth on this subject and its implications.
