Here we go again
Oh well. What can I say. New site, yadayada. It had to happen some time.
Switching back to a static site generator. Jekyll, which took me a while to decide on. In the end, Ian Mulvany rang true. Jekyll is trivial to set up (I'm using Poole/Lanyon), hosting on GitHub pages, some simple CI via Travis).
I thought about exploring other static-site generators (in particular JS-based ones) but, in the end, Jekyll is the static-site generator so it's easy to switch to and from if I need to.
I'm not yet going to switch the old site over since I have yet to properly import the older content, set up redirects etc.
