What skills doth a good developer possess?

At the bottom of the table humility is marked as a "must have" for everyone. I disagree completely. I'm from the "laziness, impatience, and hubris" school of thinking popularised by Larry Wall: http://en.wikipedia.org/wiki/Larry_Wall#Virtues_of_a_program...

I'm not trying to argue that people are justified in being rude, cruel, or impolite as a matter of course. It just takes a certain degree of arrogance to look at the state of the world and declare that you can do better. Yet innovation would never happen without people doing exactly that.
