Wales also appointed an arbitration committee to rule on disputes. Before a case reaches the arbitration committee, it often passes through a mediation committee. Essjay is serving a second term as chair of the mediation committee. He is also an admin, a bureaucrat, and a checkuser, which means that he is one of fourteen Wikipedians authorized to trace I.P. addresses in cases of suspected abuse. He often takes his laptop to class, so that he can be available to Wikipedians while giving a quiz, and he keeps an eye on twenty I.R.C. chat channels, where users often trade gossip about abuses they have witnessed.
Five robots troll the site for obvious vandalism, searching for obscenities and evidence of mass deletions, reverting text as they go. More egregious violations require human intervention. Essjay recently caught a user who, under one screen name, was replacing sentences with nonsense and deleting whole entries and, under another, correcting the abusesall in order to boost his edit count. He was banned permanently from the site. Some users who have been caught tampering threaten revenge against the admins who apprehend them. Essjay says that he routinely receives death threats. There are people who take Wikipedia way too seriously, he told me. (Wikipedians have acknowledged Essjays labors by awarding him numerous barnstarsfive-pointed stars, which the community has adopted as a symbol of praiseincluding several Random Acts of Kindness Barnstars and the Tireless Contributor Barnstar.)
Is Wikipedia accurate? Last year, Nature published a survey comparing forty-two entries on scientific topics on Wikipedia with their counterparts in Encyclopædia Britannica. According to the survey, Wikipedia had four errors for every three of Britannicas, a result that, oddly, was hailed as a triumph for the upstart. Such exercises in nitpicking are relatively meaningless, as no reference work is infallible. Britannica issued a public statement refuting the surveys findings, and took out a half-page advertisement in the Times, which said, in part, Britannica has never claimed to be error-free. We have a reputation not for unattainable perfection but for strong scholarship, sound judgment, and disciplined editorial review. Later, Jorge Cauz, Britannicas president, told me in an e-mail that if Wikipedia continued without some kind of editorial oversight it would decline into a hulking mediocre mass of uneven, unreliable, and, many times, unreadable articles. Wales has said that he would consider Britannica a competitor, except that I think they will be crushed out of existence within five years.
