Although I haven't tried getting a nontechnical user to try it, I spent some time doing just that for my personal site (editing an Octopress blog on Github, with a continuous deployment server compiling it), and I didn't like it. The whole setup felt very fragile, it was impossible to write drafts (I would compose drafts as text files on my local machine), and in the end the Github editor simply leaves somethin to be desired when it comes to UX for blog-post-writing. A better solution would be to have a raw Jekyll blog on github that you can edit directly, no special setup necessary. An even better solution (imo) is to have a blog set-up with continuous deployment, and let the user edit the content in a nice local text editor via SFTP.
