Diaspora is a free personal web server that implements a distributed social networking service. Installations of the software form nodes (termed “pods”) which make up the distributed Diaspora social network.
Diaspora is intended to address privacy concerns related to centralized social networks by allowing users set up their own server (or “pod”) to host content; pods can then interact to share status updates, photographs, and other social data. It allows its users to host their data with a traditional web host, a cloud-based host, an ISP, or a friend.
