Being an Emacs guy, I can recommend weblorg - I guess most people haven't heard about org-mode indeed, but it's one of the biggest reasons I stuck to Emacs, worth a look.

Got curious what this guy uses for the site, but couldn't find a public repo for it with a few minutes of digging. Mostly you couldn't really tell what static site generator someone uses unless it's one that supports themes, and they use one of the popular ones.
