ArbCom is weak, and loathe to make any decision that might trigger a backlash. They are incapable of dealing with serious, long-term problems and seem able only to address minor issues that would otherwise resolve on their own. The English Wikipedia is ungoverned and ungovernable, and the norms of behavior are too palsied to make enforcement of policy even slightly consistent. The whole endeavor makes more sense if we simply accept that it exists in a state of anarchy and that this will likely not change.
