Amateur Revolution
Fast Company points out that many disciplines are being subjected to an Amateur Revolution. The essay points out that linked networks of large numbers of amateurs can come up with "more, faster, and better" where small numbers of unlinked professionals cannot. This is a perfect example of an emergent phenomenon, in that we have small pieces (the amateurs) loosely joined (via the Internet) that spontaneously self-organize (because they have similar interests and coordinate among themselves) to solve problems and share information (becuase fame and accuracy help to build high-value reputation capital in the community).
