The only issue with paper is links. Hyperlinks are nice and makes notes (and task list) a true knowledge base.
But IMHO none of that is related to the todo list, which is stuff like "7 · Fred's birthday". It's about remembering things that I need/want to do, and in a way that's tactile and I can reflect on it whether I'm using the computer or not, not trying to maintain a knowledge base of everything.
Forgetting to check TW is the big reason it didn't work, but the secondary reason is that I take a lot dev logs on context and the `annotate` command is too clumsy to be practical for that.
I like the idea of a CLI tool for todos, but it needs to integrate with my notes.
