oppsummeres godt av David Weinberger i JOHO:

The media have a cognitive problem with a publisher of knowledge that modestly does not claim perfect reliability, does not back up that claim through a chain of credentialed individuals, and that does not believe the best way to assure the quality of knowledge is by disciplining individuals for their failures. […] With Wikipedia, the balance of knowing shifts from the individual to the social process. The solution to a failure of knowledge (as the Seigenthaler entry clearly was) is to fix the social process, while acknowledging that it will never work perfectly.
