In general, the best advice I can give people is to take criticism seriously, apologize for anything you have done wrong, and pull back from conflict. Of course, if you are right on a content matter, you should press forward in the interest of quality, but conflict often has a way of taking on a life of its own, unfortunately.
The goal is to give people a free encyclopedia to every person in the world, in their own language. Not just in a 'free beer' kind of way, but also in the free speech kind of way.
