Video: The power of introverts video resonates with online audience The video's lack of cute animals or children, comical accidents or even Gangnam Style dancing has not stopped it from being viewed well over a million times since it was posted to video sharing site YouTube on Nov 27. The video is based on a book Quiet: The Power of Introverts in a World That Can't Stop Talking by Susan Cain. The film's voice over, provided by the illustrator of the cartoons Daniel Widfeldt Lomas, explains that today's culture prizes being socialable and outgoing, while being quiet and contemplative can be seen as lazy, difficult, even shameful.
