The general focus of this dissertation revolves around the question whether our sense of partecipation to contemporary historical events is effectively being facilitated or nor by the media we are using. In particular, what kind of history does the e.g., Facebook/Twitter record 2011 Tahrir Square Egyptian protest represent? Does it produce an evidence of partecipation in what? Should Tahrir Square be considered a "new communication space" which is extended by social media and instant messaging services?
