At the time the article was originally published, I read that it says "It's a pseudonym the 30-year-old Silicon Valley IT professional uses as he documents the inner machinations of the project, along with a dozen other Wikipedia administrators, on a site called WikiTruth (www.wikitruth.info)." So I went over to the wikitruth site and called up the Special:Listusers page. Surprise surprise, there were only 8 registered accounts on the wiki, only one or two of which were active. I would be genuinely surprised to find more than one "Wikipedia administrator" on the entire site, rather than a group of disgruntled trolls and banned Wikipedia users (the makeup of every other anti-Wikipedia site to date).
