Nico ? La ! writes "Aaron Swartz questions Jimbo Wales' (Wikimedia's founder) belief and evangelized truth that only around 500 people are the most important contributors to Wikipedia. Whereas the truth is that they probably are the people who do the most editing. From the post: 'For example, the largest portion of the Anaconda article was written by a user who only made 2 edits to it (and only 100 on the entire site). By contrast, the largest number of edits were made by a user who appears to have contributed no text to the final article (the edits were all deleting things and moving things around).'"
Which ultimately means that Wikipedia in some ways much more closely mimics a real encyclopedia, with many contributors writing the bulk of the content, but a small group massaging that text to insure standards compliance with the overall work. Interesting thing there and worth your time, although the super-computer thing doesn't make a lot of sense to me.
