This report presents the major outcomes of a validation and policy options workshop on social computing, held at IPTS in Seville, on 26-27 February 2008. It points to a number of relevant issues (including methodological and conceptual ones) that need to be taken into account in a study of the socio-economic impacts of social computing. It argues that there is little room for direct policy interventions in social computing but that framework conditions and impacts at sector-level (e.g. education, government) need to be considered. The report also discusses the future of social computing and the opportunities it offers Europe.
