Since Sanger parted ways with Wikipedia in 2002, he has been critical of its accuracy, among other things. In December 2004, Sanger wrote a critical article for the website Kuro5hin, in which he stated that Wikipedia is not perceived as credible among librarians, teachers, and academics when it does not have a formal review process and it is "anti-elitist". In September 2009, Sanger mentioned one reason for distancing himself from Wikipedia: "I thought that the project would never have the amount of credibility it could have if it were not somehow more open and welcoming to experts." He pointed out, "The other Problem was the community had essentially been taken over by trolls to a great extent. That was a real Problem, and Jimmy Wales absolutely refused to do anything about it." Wales responded by stating, "I think very highly of Larry Sanger, and think that it is unfortunate that this silly debate has tended to overshadow his work."
