Changes

After experimenting with Nupedia, which relied on approved editors for quality control, Wikipedia founder Jimmy Wales concluded that a top-down "cathedral" development model would not allow the project to be successful. Wales sought a method whereby a larger group of users could asynchronously or simutaneously simultaneously review content. Wiki software, which allows the easiest possible casual users easier access to editing by even casual userstools, was Wikipedia's solution offered Wales an alternative to the problems presented by he say in the Nupedia model. Wikipedia soon developed a large group of regular users who exercise control controled content by reviewing recent changes and individual watch-listsof users they did not trust.

In a reversal of contrast to the Nupedia model, in which edit privileges were difficult to come by, at Wikipedia, everyone has offered edit privileges by default, and administrators revoke revoked edit privileges at their discretionbased on policies, and their opinion of content or contributors.
