Algorithmic Citizenship is a new form of citizenship, one where your citizenship, and therefore both your allegiances and your rights, are constantly being questioned, calculated, and rewritten.
Citizen Ex is an extension for web browsers which makes visible the physical infrastructure that underlies the internet, mapping the location of web sites, and visualising the user's "algorithmic citizenship". An accompanying website includes more background on the nature of citizenship, and essays on digital human rights issues.
Citizen Ex was installed by thousands of web users in the week of its launch, and continues to be in active use. It was covered extensively by international media, including Vice, Good, New Scientist, ICA, Nouvel Observateur, Corriere Della Serra, and Wired.
