I am a graduate student at UC Santa Cruz in California. I work on the WikiTrust project, studying reputation systems and other metrics derived from the Wikipedia edit history. We are making the results of our calculation available to the public through a Firefox WikiTrust add-on, which will add a new tab to Wikipedia pages to display our computed trust values.
We recently completed an analysis of the English Wikipedia (and already have the Polish and French versions completed). If you would like to help us out, please beta-test this software and send us feedback on what improvements could be made. We appreciate all the community enthusiasm and support we have received over the years, and hope that this can become a useful tool to others.
