Why Not? How to Use Everyday Ingenuity to Solve Problems Big and Small This is the name of a new book, by Ian Ayres and Barry Nalebuff (who were interviewed this morning on NPR’s Weekend Edition), respectively professors of law and business at Yale. It is also, apparently, the name of a movement of sorts. They are ‘open sourcing’ their notion and inviting contributors to share design and innovation concepts in the public domain. See the website.
