I understand the no js/plugins, but why not a static site generator?
Static site generators (at least most) are the only "new" technology that seems to make things simpler instead of more complicated, and SSGs are a massive time saver regarding themes, sitemaps, robot, optimization, etc.. and there are no dependencies at all.
It also helps me writing.
I run `hugo serve` that autorefreshes in the background, then I have split up my screen with right being my vim and right my browser.
Takes 1 second to see the result of what I am doing.
I think that's how I will write my blog posts too. Whenever I want to write a post (that won't be frequent) I'll just add a html page in my /blog dir on github pages and link it on /blog.html with date/title and all. I am sure there are tons of such blogs out there. And then I will request OP to donate to Internet Archive :)
