Taxonomy of Social Network Platform Affordances for Group Interactions

In this paper we investigate the mutual shaping between social network platforms and social interactions by developing a taxonomy of relevant affordances. More broadly, this taxonomy will eventually serve to answer the question: which platform affordances influence norm building behaviour in groups? The relevant affordances we identified are ‘network interactions’, ‘interventions’, ‘ephemerality’ and ‘visibility’. These affordances are complementary to 3 of boyd’s (2010) structural affordances of networked publics.
