As Ben DeJarnette writes in the kick-off piece to this special series, “There perhaps was no journalistic buzzword more widely discussed in 2015 than ‘engagement.’” The series, writes DeJarnette, was inspired by Experience Engagement, a four-day participatory “un-conference” hosted by Journalism That Matters and the Agora Journalism Center. Over the next two weeks, this series will explore the progress, promise and potential challenges of community engagement in journalism.
