I think that in the long run, one of the most important things for us to do is preserve and extend our culture of co-operation, with all of us standing as firmly as possible against the culture of conflict embodied in Usenet.
Don't get me wrong -- I love Usenet. But Wikipedia is not Usenet, and should not become a forum for debate, especially not debate about Wikipedia. That's as bad as a Usenet flamewar about Usenet flamewars! :-)
Of course there will be disagreements and debates about what belongs on a particular page. But we should all endeavor to keep ourselves focussed on the _end_, i.e. a well-rounded, complete, and high quality encyclopedia. Wikipedia is not h2g2 or everything2. The community is essential to achieving the goal, but the community exists in the service of the goal.
