To jump on the bandwagon:
Yes, the article generalized way too much about what it's like to be introverted, especially since it name-dropped MBTI's brand of introversion. I score very high on introversion, yet I am able to do very well in meetings and in dialogs where there's an actual focus to them. I'm never afraid to speak up, and if anything, I can end up talking the most out of a group.
Nonetheless, there are other aspects of the article that are enlightening--like the research on the brains of introverts compared to extroverts. I personally liked the part about small talk, notably, the part where it brings up what not to ask an introvert; although, I do feel as though it presents an overgeneralized view of an introvert's reaction that makes it seem as though introverts can't even begin to cope with the tiniest change in environment or conversation.
Oh well, you win some, you lose some.
