Constructing Digital Democracies: Facebook, Arendt, and the Politics of Design:

Deliberative democracy requires both equality and difference, with structures that organize a cohesive public while still accommodating the unique perspectives of each participant. While institutions like laws and norms can help to provide this balance, the built environment also plays a role supporting democratic politics—both on- and off-line. In this article, I use the work of Hannah Arendt to articulate two characteristics the built environment needs to support democratic politics: it must (1) serves as a common world , drawing users together and emphasizing their common interests and must also (2) preserve spaces of appearance , accommodating diverse perspectives and inviting disagreement. I, then, turn to the example of Facebook to show how these characteristics can be used as criteria for evaluating how well a particular digital platform supports democratic politics and providing alternative mechanisms these sites might use to fulfill their role as a public realm.
