This is what I've been working on lately: https://glue-rs.github.io/
The content of the site isn't what I've been focused on, but the underlying technology.
First I wrote my own parser combinator framework: https://crates.io/crates/glue
Then I wrote my own markup language: https://crates.io/crates/etch
Then I wrote a static site generator to pull the bits together: https://github.com/glue-rs/website
