"I work for MegaCorp. We have developers here that are incredibly difficult to get along with and a few that are great. There seems to be this sense that the more capable and intelligent a person is the more frequently they're jerks to deal with. I haven't found this to be true. There are plenty of good devs that aren't "holier than thou" (and one of the best devs I worked with was clearly on the extroverted side, though most of them land on the introverted side of things)."

I agree with you here. I also find that the jerks, may seemingly be intelligent, but don't learn much from other people (which usually happens if you are smart+socially aware) because they think are right all the time
