Prankster unmasked A Tennessee man has admitted to posting a spurious biography of veteran editor John Siegenthaler, Sr. on Wikipedia.org. I described the incident in a post about a week ago. There's a story about the admission here. Apparently, there was no harm intended. The story said the prankster changed the entry to play a trick on a co-worker, although why he chose Mr. Siegenthaler to be the victim isn't explained. Wikipedia got a lot of grief over the incident and event went so far as to tighten its submission rules to prevent a recurrence.  ¶ 8:54 AM
