I've taken a different approach to solve this problem (http://substancehq.com/). It uses mustache but does the rendering on the server side. My aim is to make it a lot better thank jekyll, because in my experience, jekyll doesn't have the best feedback cycle for editing → publishing. Sure, you can use the editor you like to write the blog posts, but, polishing them after publishing is a realy pain. Would love to hear feedback about it :) http://substancehq.com/
