" Jack and Ev looked at each other for a moment in the boardroom. At that moment neither realized that they were both fundamental to what Twitter had become. The perfect equilibrium of two different ways of looking at the world: the need to talk about yourself, compared with the need to let people talk about what was happening around them. One could never have existed without the other. That balance, or battle, had created Twitter. A tool that could be used by corporate titans and teens, by celebrities and nobodies, by government officials and revolutionaries. A place where people with fundamentally different views of the world, like Jack and Ev, could converse. "
