Each subject area is controlled by a relatively small number of people. There are about a dozen editors on each side of the Israeli-Palestinian issue who duke it out at each related article. There are about two dozen centrist Democrats who own most modern American politics articles. As a whole, Wikipedia may be edited by a large number of people, but if you spend any time editing any given subject area, you get to know the one or two dozen people who control it pretty quickly.
