>nearly all of Wikipedia is written by just 1 percent of its editors Is this true? I've heard a counter-argument to this in the past that Wikipedia works much like other encyclopedias do, a large number of domain specialists contribute large blocks of text about their respective fields (perhaps in just one edit) and then a core group of "editors" go around adjusting style, adding "[citation needed]" and making it all fit together (many many edits).
