Wikipedia is first and foremost an effort to create and distribute a free encyclopedia of the highest possible quality to every single person on the planet in their own language.
It's good to let your ego be punctured once in a while. Most of us, after several years and tens of thousands of edits, start to put a lot of our egos into our work here, more than we originally either intended or anticipated. While it's natural for this to happen, the unintended consequences include feelings of ownership over one's contributions and a quickness to react in poor faith, and even with arrogance. Someone reverted your edits with a sarcastic edit summary? Let it go. Someone called you a bad name somewhere? Don't retaliate. Let it go. While it hurts at first to let these things go, being able to do so is the true test of strength and maturity. You only gain in the long run. Retaliating not only brings you discredit, but it increases your anger, and corresponding risk of over-reaction, as the number of related provocations rises.
