Readers of this magazine will be familiar with the emergence and proliferation of a new form of value creation, peer production (as first defined by Yochai Benkler), in which communities of volunteers (but also in fact mostly paid creators and programmers once a project is successfull) create (open) content or (free) software, that is usable and accessible by everybody. Typical for peer production is that the producers create products (with both concepts being essentially misleading in this case!) in such a form that they form a commons which can be used and modified by others, who return it improved to the same common pool. These producers can be volunteers or paid programmers or authors, often both operating as a cooperative ecology between communities and the companies that create market-based spin-offs from that same commons. As a typical example, Linux and its derivatives come to mind, which have created a $36 billion economy.
