+
+What is GNU MediaGoblin
+=======================
+
+Three years ago, 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 own their data and that measn someone has to build
+the tools to make it possible.  We decide 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.

+How is this licensed?
+=====================
+
+FIXME - write this once we work out the details
+
+
+Is this an official GNU Project?  What does that mean?
+======================================================
+
+We are!  It means that we meet the GNU Project's rigourous standards
+for free software.  To find out more about what that means, check out
+`the GNU site <http://gnu.org/>`.
