The past few decades have witnessed the growth of movements that use digital means to connect with broader publics and express their point of view. Social media facilitate feelings of engagement, in ways that frequently make people feel reenergized about what it means to be political. In doing so, media do not make or break revolutions but they do lend emerging, storytelling publics their own means for feeling their way into the developing event, frequently by making them a part of the developing story. Digital technologies network us but it is our stories that connect us to each other, making us feel close to some and distancing us from others. Affective Publics explores how storytelling practices on Twitter facilitate affective engagement for publics tuning into a current issue or event by employing three case studies: Arab Spring movements, various iterations of Occupy, and everyday casual political expressions as traced through the archives of trending topics on Twitter.
