We at WeAreTeachers are greatly influenced by the ideas of "The Long Tail". We are very interested in enabling Long Tail economics for the world of educational products using the incredible resource of the worldwide teaching community. Both these new books extend and explain Long Tail concepts.
The first is The Black Swan: The Impact of the Highly Improbable
by Nassim Nicholas Talib. This highly anticipated book describes how large changes happen due to 'improbable" events that change our understanding. Evolution, History, Economy, and Society all "jump" when these things happen and enormous opportunities are presented.
The 2nd Book is Everything Is Miscellaneous: The Power of the New Digital Disorder
by David Weinberger. This book expounds on the concepts of dealing with complexity by communities organizing information from widely disparate sources. The result is a much more powerful way to make choices and deal with today's almost infinite variety. I've been lucky enough to meet to collaborate with Dave and I always welcome his insight.
