He's not a doctor, but he plays one on the web MAR 01 2007
The letters to the editor section of the New Yorker this week contains a correction to Stacy Schiff's piece in the magazine about Wikipedia from July 2006. The piece included an interview with Essjay who was described in the article as a tenured professor with a Ph.D. Turns out that Essjay wasn't exactly who he said he was:
At the time of publication, neither we nor Wikipedia knew Essjay's real name. Essjay's entire Wikipedia life was conducted with only a user name; anonymity is common for Wikipedia administrators and contributors, and he says that he feared personal retribution from those he had ruled against online. Essjay now says that his real name is Ryan Jordan, that he is twenty-four and holds no advanced degrees, and that he has never taught.
The full editor's note is appended to the original article.
