+What is GNU MediaGoblin
+=======================
+
+Three years ago (2008), a number of free software luminaries got
+together at the FSF office to answer the question, "What should
+software freedom look like on the participatory web?"  Those thinkers
+included Richard Stallman---founder of the free software movement and
+instigator of the GNU project, Evan Prodromou---the driving force
+behind Status.net, a highly sucessful federated micro-blogging
+service, and FIXME.
+
+Since that time Identi.ca and Libre.fm have answered the
+freedom-loving web-user's need for micro-blogging and music sharing.
+Now, GNU MediaGoblin is building a format for users to share photos.
+Later versions of MediaGoblin will include support for video and other
+media as well as tools to encourage collaboration on media projects.
+
+
+Why are we doing this?
+======================
+
+Centralization and proprietization of media on the internet is a
+serious problem and makes the web go from a system of extreme
+resilience to a system of frightening fragility.  We believe people
+should be able to free their data from proprietary control and that
+means someone has to build the tools to make it possible.  We decided
+that in this case, that someone would be us!
+ 
+
+Who are you?
+============
+
+Free software activists and folks who have worked on a variety of
+other projects like Libre.fm, GNU Social, Status.net, Miro, Miro
+Community, OpenHatch and other projects as well.  We're admirers and
+contributors.  We're writers and painters.  We're friendly and
+dedicated to computer user freedom.
