I've read her book (Quiet: The Power of Introverts in a World That Can’t Stop Talking.); it's a good read, especially so for anyone who identifies with what the article speaks of but hasn't ruminated on it too deeply before. Goes double, really, because if you haven't had time to think on it you're probably becoming increasingly frustrated without realizing why.
Take anything anyone claims to tells you about yourself with a grain of salt, of course, but I found it interesting.
