I actually thought about doing a larger study (like whole language editions) on exactly that question myself with the wikiwho tool [1] that we developed for that purpose, but didn't find the time yet. But if anybody is interested in conducting such a study I would certainly be interested to assist (or to know if you find someone that has already done it). 

Cheers, 

Fabian

Hi all,

I wonder if you know if somebody verified and / or further researched
Aaron Swartz's thesis on structure of Wikipedia participation. You can
find it here: http://www.aaronsw.com/weblog/whowriteswikipedia

Best,
Krzysztof Gajewski
