The science behind the creation of Wikipedia entries

Aaron Swartz has done some data-crunching using a rented supercomputer cluster to find out how Wikipedia entries get written. It turns out that there is a cluster of around 500 core editors who tidy up the majority of entries that are created by unregistered drive by posters.

This is interesting data for an organisation who run their own Wiki, as the number of core editors compared to the number of posters is very small.
