For those who missed the live stream (and for posterity), the presentation by AskHistorians at the 2016 American Historical Association meeting in Atlanta, GA is presented here in full. The title of the panel session was “AskHistorians”: Outreach and Its Challenges in an Online Space and featured five presentations on how AskHistorians has created, grown, sustained, and moderated an online space for historical discussion.
