This document discusses six forms of crowdsourcing that could be applied to urban planning: 1) Distributed data collection, 2) Soliciting design solutions, 3) Collective intelligence, 4) Peer production of public goods, 5) Collective Intelligence Genome, and 6) "Open Innovation" Technology. It notes that while these approaches have the potential to engage the public, they also have naïve views of government that could lead to libertarian ideals if not implemented carefully. New technologies should be considered as part of planning, but traditional institutions still need to be involved to ensure proper social and political outcomes.
