Joel West recently attended the 8th Annual International Open and User Innovation Workshop. In one of the papers, he reports, Hind Benbya and Marshall Van Alstyne explained how crowdsourcing can be used to create internal markets for knowledge using the two-sided market perspective to match buyers and sellers - as in external crowdsourcing. Having previously argued that 'crowdsourcing better fits the user innovation paradigm or open innovation paradigm', West now thinks that 'it's more of a process or set of skills, enabled by an understanding of the two-sided market framework ... In other words, crowdsourcing is really about systems and incentives, not any great new theory.'
