For example, Benkler argues that blogs and other modes of participatory communication can lead to "a more critical and self-reflective culture", where citizens are empowered by the ability to publicize their own opinions on a range of issues, which enables them to move from passive recipients of "received wisdom" to active participants. Much of The Wealth of Networks is presented in economic terms, and Benkler raises the possibility that a culture in which information is shared freely could prove more economically efficient than one in which innovation is encumbered by patent or copyright law, since the marginal cost of re-producing most information is effectively nothing.
