The notes themselves are useless, IMO. Only through writing them do you get the uncluttered mind.
Maybe if you write good enough notes others will organize their thoughts through yours, though with diminishing returns.
If notes don't lead to actions, then they're doubly useless, and that's what usually happens when you're flipping through others' thoughts: a bunch of "takeaways" but rarely any "that's what I'll do today"
