A couple years ago, I undertook a similar thing: Makefile + discount: more-modest, with some discussion about it here. It’s been well worth it, make implementations not withstanding.
I personall use hugo, which works reasonably well. What I like is the option for taxonomies, which allow you to specify series and create arbitrary groups for posts. And it also accepts files written in org-mode!
I tried Pelican and I am trying Hugo at the moment. The thing I find annoying about all these static site generators is that they are very focused on blogs. It’s almost impossible to find a good theme that suits a simple multi page website with a logo.
My current website runs on a 20 line php script with Slimdown, which is a simple regex based Markdown parser in php. Works pretty well for my needs. :)
Needs an RSS feed!
It now has an RSS feed an a sitemap :)
