Not speaking for the GP. I use MkDocs and keep my personal notes. The only weak spot for me is that I haven't fully grokked search and as my notes grow, it can be harder to find things. I alternate between figuring out how search and how to bolt on some other search utility.
MkDocs includes a utility to publish to Github pages but I keep my notes on a self hosted Gitea server and serve using "python -m http".
