For the past few months, I've been keeping notes in Obsidian, and I decided that I wanted to share them; mostly for my own reference, but also in case they're useful to anybody else.
Thus notes.billmill.org was born.
A feature I really enjoy about Obsidian is that it stores documents as folders of markdown files, so that should I ever decide to leave the app, all my notes can follow me to whatever I use next.
That feature also makes it easy to do what I've done with notes.billmill.org - write a simple program that goes through all my notes files and publishes them as HTML.
You can find the code for publishing the site on github, but I don't think it is likely to be too valuable to anybody but myself. The site is published on a highly technical schedule of "whenever I decide to run make publish".
