Although Aristotle's ethics have been refuted by many philosophers, both ancient and modern, the Aristotelian mean provides an interesting model for considering how best to operate in a community. This page lists some seemingly contradictory ideals that have come up for community (especially with regards to Wiki).
I was thinking about some of the great ideas that come up on this and other wikis about how to interact with a community, and how they are often contradictory. I think that achieving an AristotelianMean between opposing suggestions can help get the best results for a community. This page is kinda shallow, but I'll try to add some more ideals as I see them.
