AskHistorians is an all-volunteer, multi-platform new media forum with over 350,000 subscribers, making it the largest historical space of its kind on the internet. Unlike most outreach, the forum is structured like highly public “town hall meeting” on a global scale—a question-and-answer session in which knowledgeable experts publicly interact with individual questioners while an audience watches. By inviting individual lay readers to ask a question, AskHistorians allows them to set the topic and thus direct their own learning. By making it public, other interested parties can both learn from and join in the discussion to take it in new directions, fostering total engagement.
