“There are multiple things,
① Card system, I think this is just an awesome way of writing notes that helps me focus on the essentials.
② Community / Support, I really got a lot of help from the founders.
③ Linking, tagging, parenting etc. I love this system in the way it connects my thinking to help me better understand the fundamentals and the relations between them.
④ API since I love programming, It's a great system for me to add on to my notes and my note-taking.”
