The Citizen Ex browser extension guesses where you’re geographically located on the web. That is, it guesses where the server — the one you just pulled that website from — is in the world. It also guesses where you are physically located. The extension keeps track of these locations and computers something called Algorithmic Citizenship.
Algorithmic Citizenship is a form of citizenship which is not assigned at birth, or through complex legal documents, but through data. Like other computerised processes, it can happen at the speed of light, and it can happen over and over again, constantly revising and recalculating. It can split a single citizenship into an infinite number of sub-citizenships, and count and weight them over time to produce combinations of affiliations to different states.
