Using social media platforms to build informal learning processes and social networks is significant in academic development practices within higher education. We present three vignettes illustrating academic practices occurring on Twitter to show that using social media is beneficial for building networks of academics, locally and globally, enhancing information flows, inspiring thinking, and motivating academic practice. Using a reflective and diffractive methodology, we illuminate how different flows of forces and relations are enacted. We argue it is in this fluidity of informal learning that perspectives are contested and shaped, and that academic developers can benefit by encompassing such practices.
