John, I have to disagree. I think the Big Shift holds enormous opportunity for introverted people, insomuch that introverts tend to be more introspective. If we indeed are experiencing a shift from explicit knowledge to tacit knowledge, we need more of the deep-thinking "mental processors" like yourself, Clay Shirky, Andy McAfee, etc to make sense of all this information. Furthermore, I think introverts tend to fare better for creating deep relationships as they are more discriminating (extroverts tend to skim the surface of many relationships). These deeper relationships yield more trust and, as a result, are longer-lasting and more productive.
