The document discusses the concept of wikinomics and how it can be used for innovation. Wikinomics is defined as harnessing mass collaboration for innovation, growth and profit. Examples provided include Wikipedia, which uses mass collaboration to build its knowledge base, "brute force attack systems" like protein folding games that crowdsource solutions, and open source projects where scientific communities collaborate to solve problems. The significance is that mass collaboration can lead to innovation when the value of collaborating outweighs not collaborating.
