Citizendium is based on the failings and unreliability of Wikipedia. - Larry Sanger

Wikipedia lacks the habit or tradition of respect for expertise. As a community, far from being elitist (which would, in this context, mean excluding the unwashed masses), it is anti-elitist (which, in this context, means that expertise is not accorded any special respect, and snubs and disrespect of expertise is tolerated).

Basically, the Left tends to invade open institutions, it's been their modus-operandi for the last hundred years. Basically, invading open institutions and subverting them, dominating them, and freezing out anyone who dissents their views. I can't tell you what the cause of the bias on Wikipedia is, I can only tell you that it's really obvious now. It used to be quite obvious 10 years ago, now it's just embarrassing... Now there is an official view about pretty much everything...

It's become both opaque and centralized, centralized in the sense that the authority to participate in Wikipedia has been greatly restricted. You can be completely anonymous and even be a top-ranked Wikipedia user with administrator rights. So, they could be working for various corporations, various government spy agencies, maybe for criminal organizations.
