I’ve done some thinking about this myself. It has also struck me lately by the number of times in podcasts of interviews with experts I’ve lately hears someone say “I don’t have all the answers,” or something like this….

I also think Graham’s answer above is true, the question of “flattening” and who gets to become an expert is interesting. When guys like me, from a small town inthe middle of nowhere, can write a blog that has over 90 subscribers, I’m scared about how we “make” experts. The potential of the number of voices we have and the number of experts that we can have (the latest estimates of the number of people online is around one billion) is astonishing. We must be prepared to read far and wide.
