One of the main challenges for the first GNU social Camp was to develop an alternative to the centralization of the collaborative economy using GNU social, a free standard for the development of distributed web applications. Sharings—a plugin for GNU social— creates the possibility of adding objects and services to GNU social to share them with the users on your node or, if they’re on other nodes, connected to you through federation. Sharings is still in alpha, but it already allows you to share objects, and other users can show interest in the object that you’ve shared and get in contact with you to agree on the details of the exchange.
