I dunno if it will help, besides maybe for some ideas, but when I created my blog a year or so ago, I wanted something like a site generator without running anything on the backend.[1] I ended up doing everything in CSS/HTML/JS/JSON. JSON is used to store posts. I write a post normally using HTML, then use a tool to format it for JSON. Doing it this way allows my static site to run amazon for dirt cheap. Updating the site is just uploading a new JSON file.

I wish I would've developed it further to allow for markup to be used, but other projects always come up.
