Warren Buffett is certainly not an introvert if you've ever seen him speak, and his history also suggests he's not an introvert. He was a door-to-door salesman as a young man.
Introverts can be great speakers and very social beings. It's just that doing so bears a cost that extroverts never understand.
Introversion manifests itself in that interacting with people and presenting yourself in the public will drain your energy levels. Introverts need to recharge themselves alone (or with immediate family only) for a few days after being overly social. If Buffett would just prefer to stay home and do his own things for a couple of days after presenting at each of his quarterly reports, he's likely to be an introvert.
