In higher education today, the intersection of digital technologies and changing work conditions creates intersecting, well-documented trends towards massive course experimentation, shifting funding structures, teaching precarity, and TEDtalk celebrity on the speaking circuit. Against this backdrop, the roles of academics and scholars within the larger public sphere are changing (Siemens, 2008). One way in which scholars navigate these shifts is by forging identities via online networks (Veletsianos, 2013): by building reputations and networks as scholars within the new, open, online public sphere. This paper posits that blogging and social media participation constitute a new indicator of academic influence, both within networked circles and beyond, creating visibility and reputation that funders and media may recognize. But what kinds of identity positions count as influential, credible, and valuable within networked participatory scholarship? How do scholars “read” each other’s signals in this complex new public sphere?
