From Wikipedia:
Occasionally, Wikipedians lose their minds and get into edit wars over the most petty things. This is to document that phenomenon. This page isn’t comprehensive or authoritative, but it is designed to show the “worst-case” result of people attaching so much importance to some trivial detail that they are willing to engage in the lame pastime of edit warring over an even lamer cause. Back in the good old days, people settled this sort of thing with a gunfight. Now they do it by screwing with an encyclopedia. Truly, the Wikipedia outlook has changed the way things get done. Specifically, it has changed them from actually getting done to never getting done. On the other hand, nobody gets shot, either.
