'Wikinomics: How mass collaboration changes everything" is a good book for business managers who want to understand the latest trends in technology and society.

The book refers to the InnoCentive website, as an example of idea marketplaces. InnoCentive describes its self as web-based community that believes in the power of open innovation, bringing together creative minds to create breakthrough solutions that touch every human life.

The key concept from this book is the chapter on platforms for participation, which is the concept of 'you get more from sharing than from secrecy', stressing the importance of understanding the huge advantages of building networks of active participation [3].
