> It’s best to create notes which are only about one thing—but which, as much as possible, capture the entirety of that thing. > The notion is quite similar to the software engineering principle of __separation of concerns,__ which suggests that modules should only be “about” one thing, so that they’re more easily reusable. But likewise, if you fragment modules too much, you’ll have a cohesion problem.[^am1] [^am1]: [[@Andy Matuschak]]'s [Public Notes](https://notes.andymatuschak.org) See also: [[public/99-Meta/Evergreen notes]]
