This book investigates the interplay between media, politics, religion, and culture in shaping Arabs' quest for more stable and democratic governance models in the aftermath of the “Arab Spring” uprisings. It focuses on online mediated public debates, specifically user comments on online Arab news sites, and their potential to re-engage citizens in politics. Contributors systematically explore and critique these online communities and spaces in the context of the Arab uprisings, with case studies, largely centered on Egypt, covering micro-bloggers, Islamic discourse online, Libyan nationalism on Facebook, and a computational assessment of online engagement, among other topics.
