Yes, it's not the fastest ssg; there's Zola for that. However, digging git history with `git log --follow` can take a moment, and the MathJaX server-side rendering takes 10 seconds on a math-heavy site. However, incremental builds are the default, and a full-rebuild is seldom necessary. What makes it beautiful is the following:
1. You don't have a metadata header, like in most SSGs; timestamp is picked out from git-history, and topics/subtopics is simply picked out from the folder structure.
2. The syntax is terse, and features like un-numbered lists is excluded on purpose, because mathematicians like to number or letter everything.
3. The implementation of claytext is simple. There is no complicated markdown-processing, and even hard-wrapped lines are not allowed.
4. There's a dedicated vscode extension for auto-completing MathJaX. It also triggers a build-on-save, so you can just save changes in vscode and refresh the browser to see the changes.
5. Server-side rendering of math, so that the client isn't burdened with executing heavy javascript. It actually uses a custom fork of XyJaX to achieve this for commutative diagrams.
