JustPublics@365 have produced some interesting skills guides for scholars who wish to build an audience for their work beyond academia. Example guides include a Social Media Toolkit, a report: Engaging Academics and Reimagining Scholarly Communication for the Public Good and thought provoking material on altmetrics.
The site is particularly interesting because of the collaborations which it encourages between scholars, activists and journalists in the pursuit of social justice.
So why not take a look at their resources here ?
