SMOB is a Semantic MicroBlogging framework that enables an open, distributed and semantic microblogging experience based on state-of-the-art Semantic Web and Linked Data technologies.

It relies on distributed hubs that communicate each other to exchange microblog posts and subscriptions (i.e. following / followers). Anyone can install his own hub and start following other users, while SMOB also allows cross-posting on other platforms such as Twitter.
