Finally, we are happy to announce that WikiTrust works on the English Wikipedia!
Just install the WikiTrust Firefox extension and visit any page.

Finally! After so many years since my wikipedia paper it is awesome to actually see this! Big ups to the Wikitrust team for making this a reality. Looking at their algorithm page it appears they decided on an approach that is different from my original suggestion:

It is possible to compute text trust also based on a mix of text age, and number of revisions for which the text has been present; in fact, it is straightforward to modify WikiTrust to do so. The reason WikiTrust uses also the reputation of authors is to prevent a well-organized set of new users from cheating the system, creating content that gains full trust due to their coordinated revisions. Since new users have low reputation, this type of attack cannot be carried out.

Great work!
