It's important to be aware that one isn't either an introvert or extravert; it's a scale. And you can move around it. I use software everyday built by (large) teams which no doubt required some extroverts to get done. In fact, I don't think I use any software written by a single person? Some people must not have worked in very good teams when I see the subject come up. Having my first proper training (it involved Belbin, but there are other models like it) openee my eyes to understanding interpersonal dynamics and what separates funtioning dynamics to non functioning ones (some diversity in attitudes and skills!). Writing great code means nothing if nobody knows about it, is able to use it, or needs it, etc. I recently organized a training like this for my current team (of highly skeptical software engineers) and it was a great succes. It would be a good start if people wouldn't reduce themselves to a single stereotype. People can be and are multiple things at once, and I'd say it's extremely healthy and useful to be skilled in more than a single way.
