To wanted to make the blog with the simplest tools and tech stack possible. The less dependencies, installation, maintaining, the better. So I looked around, and found some interesting possiblr solutions.
Plain text blogging options:
Those are all great optons. I chose to go with something even more minimalist though: just pure selft-hosted html and css. I'm using a custom version of new.css a classless CSS framework to write modern websites using only HTML. It's ~4.5kb. It's perfect for dead-simple blogs, collecting your most used links or making a simple "about me" sites. There are other similar options though.
Anyway, that's my simplest blog engine.
