Actually the Wikipedia thing has been more or less thoroughly debunked. 
Whereas it is true that a very small minority (I think about 2000 people) 
are responsible for an overwhelming number of edits, it turns out their 
edits tend to be minor in character: fixing style, citations, that kind of 
thing. Most of the contentful edits are made by people who edit little.
