After trying Hugo, I tried Hexo.

Like Docpad, Hexo is also based upon NodeJS.

Basically, you can write your posts in Markdown, HTML, EJS, like with Docpad.

It has many themes. I picked Anodyne and simplified it.
Unlike Hugo, you can easily modify the theme’s CSS (or Stylus), and when you generate the site, it also regenerate the CSS.
