This site is built with the superb static site generator Hugo. I ran into this while learning the Go language, after dabbling with Jekyll and Hyde, and I was blown away by how richly featured, mature and well documented it is.

The theme is based on Detox, by Andrew R. Jenkins, itself based on the Detox theme by Jordan Bowman for the Ghost platform. It has been heavily modified to feature a standalone homepage, updated look and feel, and to eliminate Javascript.

The font is the classic Museo by Jos Buivenga of the exljbris Font Foundry. I normally lean towards sans serif fonts, but there is something generous and pleasing, while maintaining a modern appeal, about Museo, that is irresistible.
