  We show how important phenomena in social networks like coordination, trust
and the communication of unsubstantiated information (gossip) can be modelled
and understood using epistemic networks or epinets: directed graphs comprising
networked agents and the key facts, statements or other kinds of propositional
beliefs relevant to their actions. We use epinets to sharpen the explanatory
and reach of social network analysis to situations problematic to both
network-structural approaches and epistemic game theory.
