The DC municipal government actually has a Github organization (https://github.com/dcgov https://github.com/dcgov) and has been attempting to pilot open source development (http://open.dc.gov/open-source-guidelines/ http://open.dc.gov/open-source-guidelines/) throughout the city. I helped write that document, which was inspired by/borrowed from 18F policy. Take up has so far been limited, though some agencies have been using Github Pages.
