Wikinomics: How mass collaboration changes everything by Don Tapscott and Anthony D. Williams

This is a fascinating book that has implications for both business and education.

From the jacket cover:

Today, encyclopedias, jetliners, operating systems, mutual funds and many other items are being created by teams numbering in the thousands or even millions. While some leaders fear the heaving growth of these massive online communities, Wikinomics proves this fear is folly. Smart firms can harness collective capability and genius to spur innovation, growth and success.

Based on a $9 million research project led by best selling author Don Tapscott, Wikinomics show how masses of people can participate in the economy like never before. They are creating TV news stories, sequencing the human genome, remixing their favorite music, designing software, finding cures for diseases, editing school texts, inventing new cosmetics, and even building motorcycles.
