I don't blog very often for several reasons. My technical excuse was that blogging from emacs to one of the hosted services was too painful. This is an experiment to see if I can get around it.
Org2Blog allows you to post from an OrgMode file in emacs, which is pretty nice. The only prerequisites are org mode and xmlrpc.el. The setup is pretty straightforward, as described in the README.org file.
Speaking of org and github, github appears to render README.org files in the main directory when you are viewing a repository. That is pretty awesome.
Code and latex snippets show up from org2blog too! I am fine with the default formatting, but I imagine this stuff could be tweaked to look however I wanted.
