I also wrote my own static site generator using Python [0] that I use to generate my personal site [2], and that I introduced as a blog post here [1].

Posts are written in Markdown with simple formatting, templates are HTML/CSS with Jinja2 templating, and it includes support for things like automatic table-of-contents generation for posts, blog index pagination, tags, related posts (manually tagged, for now), comments (using utteranc.es and GitHub issues), and automatic image compression/scaling/caching (between builds). Eventually, I intend to add things automated 'related posts' list generation, but haven't gotten around to it yet.
