Kind of a broad question. I wonder why people take notes - Is it for studies or learning? Is it just to remember things? Is it to make your own map of your knowledge? Is it because you just want a place to vent out your feelings into the void?
What do you use to accomplish that? App? Paper? A chat room?
I started taking notes on a app called Craft. It kind of takes a page from notion, but it is not nearly as bloated. I use it for everything, notes on books, journaling, keep tabs on my exercises and so on.
