How does Any Forums keep notes and review/study using technology?
Obsidian is convenient and easy to use for keeping hierarchical notes out of markdown files. Thinking of trying mochi for spaced repetition so I actually remember the notes without having to reference them so much. Is there better software for that?
nah, having to render notes and read them in a separate viewing application sucks. you shouldn't need the full power of a typesetting language for simple notes either. org-mode has it right. plain text and a very dead simple markup format for pretty much everything, and then inline latex and images can be rendered in the same buffer instead of compiling to a pdf and losing the power of emacs.
