+What is GNU MediaGoblin
+=======================
+
+In 2008, a number of free software developers and activists gathered
+at the FSF to attempt to answer the question "What should software
+freedom look like on the participatory web?" Their answer, the
+`Franklin Street Statement`_ has lead to the development of
+`autonomo.us`_ community, and free software projects including
+`Identi.ca`_ and `Libre.fm`_.
+
+.. _Franklin Street Statement: http://autonomo.us/2008/07/franklin-street-statement/
+.. _autonomo.us: http://autonomo.us/
+.. _identi.ca: http://identi.ca/
+.. _Libre.fm: http://libre.fm/
+
+Identi.ca and Libre.fm address the need for micro-blogging and music
+sharing services and software that respect users' freedom and
+autonomy.  GNU MediaGoblin emerges from this milieu to create a
+platform for us to share photos in an environment that respects our
+freedom and independence.  In the future MediaGoblin will include
+support other media, like video, and provide tools to facilitate
+collaboration on media projects.
+
+
+Why Build GNU MediaGoblin
+=========================
+
+The Internet is designed---and works best---as a complex and endlessly
+resilient network.  When key services and media outlets are
+concentrated in centralized platforms, the network becomes less useful
+and increasingly fragile.  As always, the proprietary nature of these
+systems, hinders users ability to develop, extend, and understand
+their software; however, in the case of network services it also means
+that users must forfeit control of their data to the service
+providers.
+
+Therefore, we believe that network services must be federated to avoid
+centralization and that everyone ought to have control over their
+data.  In support of this, we've decided to help build the tools to
+make these kinds of services possible.  We hope you'll join us, both
+as users and as contributors.
+
+
+Who Contributes to the Project
+==============================
+

+We are free software activists and folks who have worked on a variety
+of other projects including: Libre.fm, GNU Social, Status.net, Miro,

+software and network freedom.
