Web 2.0 brings to the world and to business minds the proof that opensource models (lamp, interoperability, respect to the standards, etc...) and values (openness and wisdom of crowds) can succeed. Actually it breaks the old proprietary approach by pushing mashups and remixability that needs open and standard interfaces, let say APIs. I've ordered some books about opensource philosophy today. That's why I found in my Amazon.com recommendations Innovation Happens Elsewhere. It has good reviews that helped me to find the authors provides an online version under creative commons. Good reading ;).
