I love this idea for Github and think it would be a really exciting move for them! One thought though - could the Git protocol† for editing, correcting, guest posts etc not also work well as a more general protocol for hacker bloggers?
Something like a meta tag on the index page for the blog, pointing to the git repository‡? (be it on Github, Bitbucket, or your own server) A simple command-line tool (or browser extension) would assist in checking out the repository, and you could issue the pull request with whatever communication protocols you have in common (no need to re-invent the wheel here).
† It needn't just be for git, of course - it could work with many (any?) distributed version control systems (Mercurial and Bazar spring to mind)
‡ I realise you may not necessarily want everyone to have access (even read-only) to your repository - for example, you may have future, draft posts in un-merged branches. The beauty of distributed version control is that there's no canonical server - so there's no reason the public one has to have any branch pushed to it other than master.
