This chapter considers a small data approach to understanding the transformation of audience using techniques appropriated from social network analysis in order to engage undergraduate students in reflexive patterns of self-surveillance. It argues that to be part of an audience now means to present a public persona as an interface to a network of connections. The chapter presents the analysis of a number of sociograms and other infographics generated during the course of the teaching session, in this case focusing on the subject-related hashtag #BCM112. Twitter activity and the visualization of the data thus produced is incorporated into lecture content and seminar discussions with students, leading to what is in fact a phenomenology of 'small data' audience research. This enables a reflection on the ways in which the pedagogical relations between students and teachers as digital media consumers and social media users are transforming the temporalities and spatialities of university teaching and learning practices.
