I don't think there is really anything substantive in this article, but if there is one thing we can learn from it, it's that we need to be much more clear what we're talking about when we use the words introvert and extrovert. I prefer the definition that introverts gain energy from being alone, and extroverts gain energy from being with others. People often make the mistake of coupling other things to this: shyness and introversion tend to be associated, and it leads to people saying things like "I'm an introvert there I can't (it's impossible) be a good socializer". The fact that introversion/extroversion is a spectrum certainly doesn't do us any favors either.
