I read Cognitive Surplus by Clay Shirky this weekend. My next series of posts will be quotes from it, with or without the need for additional commentary.
This speech became the first chapter to the book. It serves as a summary for the whole thing, so if you read nothing else I post from the book, it is worth spending 15 minutes listening to it. (You can watch if hand gestures help you understand speeches, but the content is almost entirely verbal.) Come back if you feel like chatting about details as we go along.
Hat tip from 2008 to the sadly departed Jeff Freeman.
