In this paper we argue for the need of a methodological framework for analysing the design of websites from a norm-critical perspective. Identifying some issues and challenges in previous studies on norms and values in interface design we suggest an approach for analysing norms in websites and user interfaces based on sociological and cultural perspectives on design. Approaching norms in interface design we understand design in terms of resources for interaction, involving four aspects of interaction: cultural representations, technology, interactivity, and context.
