My experience is that CS-educated programmers will often be more humble and ready to admit that they might not know all there is about a subject, and self-taught programmers more certain that they know the one way to solve a certain problem. Of course, this might just be the people I've met, but based on personal experience, I think university teaches you that you're _not_ the smartest one in the world, that there are lots of things you don't know, and that things are usually not as simple as they seem. That said, a lot of the self-taught programmers I know get more humble as the years go by. And of course, all the great CS-educated programmers I know learnt programming in their spare time, and got the theoretical and low-level background at uni.
