I often don't finish articles I may want to write and have a bunch of unfinished markdown files laying around. This is partly why I started writing a wiki as it doesn't have this problem.
You can find all the drafts of articles I started writing in drafts dir. For now I release the published articles on Medium but this may change in future as I am not happy with how limiting Medium is (no proper code blocks, no MDX support). I quite like Overreacted blog by Dan Abramov and I may switch to a solution like his in the future.
