Diaspora is an alternatif social network like facebook or google+. it is a free personal web serve 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. The framework, which is being built on Ruby on Rails, is free software and can be experimented with by external developers.

You can create freely an account and share content.

Afterwards, however, Salzberg and his team struggled to actually build the service. By the time they released a beta version in late 2011, Google had already come out with Google+, stealing much of Diaspora’s thunder. Over the summer, the founders decided to hand over control of Diaspora to the community and started working on a photo remixing tool called Makr.io.
