This three-day symposium is intended to explore the intersection between these two areas of inquiry, with a specific focus on how Web 2.0 is both generative and challenging of different forms of knowledge production and the authority it commands. Questions related to co-production, citizen science, the power of data algorithms and metrics to shape or bypass human agency, and the possibility of participatory forms of surveillance are just some of the issues that are raised. This conference is intended to bring together some of the leading scholars in the fields of STS, Communication and Social Media analysis, and the history and philosophy of science to critically explore these issues.
