Switching this site from WordPress to Hugo, https://github.com/spf13/hugo a static site generator written in Go. This is the first post written entirely in hugo and not imported from wordpress.
The benefits of using a static site generator include not needing a database or complicated caching, as static files can be cached very effectively, and there are no round trips to a database for content. It also removes the two biggest security issues with WordPress - attacks on the database and on PHP functions on the pages. It is, however, more complicated to setup initially, and changing things means regenerating all the static pages in the site.
