Over the past decade, academic social networking sites, such as ResearchGate and Academia.edu, have become a common tool in academia for accessing publications and displaying metrics for research evaluation and self-monitoring. In this conceptual article, we discuss how these academic social networking sites, as devices of evaluation that build on both traditional values, objects, and metrics in academic publishing and on social media logics and algorithmic metrics, come to fulfil a need in the current academic (publishing) ecosystem. We approach this issue by identifying key affordances that arise in the interaction between platform and user. We then position these affordances in relation to potential needs of academics in today’s publishing landscape by drawing on Hafermalz’s metaphor of the ‘fear of exile’, which provides an alternative way of understanding the importance of visibility in the networked world, as a combination of competitive exposure and existential recognition. We end by considering the grounds on which the platforms may be attributed some level of legitimacy. This is done in order to understand the inherent contradiction between the broad use of the platforms and the fact that their integrity has been questioned repeatedly. We seek an answer to a legitimacy for the platforms in the fact that a pragmatic, mutual benefit exists between them and the research community; a benefit that is enhanced by the audit society influencing current academia.
