ABSTRACT
This chapter explores the tensions between expertise, care, and social responsibility enacted through and within HowToBuyWiki, a Central European non-profit organization dedicated to the development of an emerging, open-source internet platform which, as the members describe it, is designed to promote 'product transparency'. HowToBuyWiki provided us with access to website analytics, as well as to various documents, including the organization's constitution, student essays written about the platform, and archived meeting minutes, through which we could trace the development of HowToBuyWiki from its inception. HowToBuyWiki members endorse a number of values central to their vision of 'conscious consumption', values that can be described under the headings of fairness and sustainability. Care practices in interventions for obesity trialled in Denmark involve combined collective efforts to alter dietary and exercise habits in ambiguous and messy collaborations between care providers and patients HowToBuyWiki offers more than an online platform to enact and reproduce already-extant relationships of care.
