I concur with the article. I've tried various tools but I keep coming back to text files in vim. Recently I've been using a notes/ directory with a bash function to quickly create and edit a named text file for a new topic. That gives me the little bit of organization and separation for isolated tasks, while still having a main notes.txt file for miscellaneous notes and todos. I really like being able to stay in the terminal and using ripgrep for everything.
