Input. I'm that guy in the corner, 5 books in front of him, each on a different subject, taking notes with both hands. If it is a social event, I'm that guy in the corner, looking a bit bewildered and trying his best to become invisible.
Actually, I do quite well giving a class or a lecture, until I have to interact with more than one human at once. I HATE the Q&A session.
