The papers in this volume all articulate a keen awareness of the shift in sociolinguistic economies caused by online technologies. We now live in an online-offline nexus of communication, and realizing this invites changes in the ways in which we traditionally view and imagine the foundations of our disciplinary approaches. In reviewing the papers, I focus on two important aspects of such revisionist enterprises. One is the emergence of an analytical triad of infrastructures, actions and moralizations, evidence of which is offered in the different papers. The second aspect is of a more general nature: we can suggest, on the basis of the evidence presented in this volume, to reverse the general heuristic of research from groups-individuals-language towards interaction-individuals-groups. This reversal of direction would equip our disciplines with an extraordinarily powerful theory of social action.
