My personal website is generated with Jekyll. I use Jekyll because it's better for links, sections, and other automated things like "related posts". It would be a tiresome task to do it all manually.
I respect this guy anyways. He wanted the simplicity and it's ok. I've see one of his posts has no CSS styling, and this is product of manual editing, you lose consistance.
The only caveats I see on this websites is, when they setup the width of the content. I love fluid pure HTML websites.
