This is interesting. I am a liaison for the Borderlands Wikia. I am glad to see that others have defined things so well about the social structures that happen on a wiki.
As liaison, I am constantly defending User Rights to edit. Also giving the hint that a particular User is an exopedian (now defined) softening that particular Users gruff responses.
I also chastise exopedians that Revert rather than clean up, banking on the pride they hold as good editors.
