Questions about note-taking are very popular on Hacker News. I am always interested in the responses. It seems like developers are always interested in the best tools and methodologies. Me too. I’ve been researching and using different approaches for decades. Over all that time, I’ve written thousands of notes, both short and long. Most notes become uninteresting after awhile and are just erased. But thousands have persisted for many years because I still refer to them.
