Don't buy into all the crazy around it. It's a Markdown editor with some organisation features. If you read Reddit, people treat it like some sort of second coming, making sure EVERY NOTE THEY TAKE is linked at least one other, tagged, etc. Like somehow that makes notes better. I was confused at first too but once I realised most of these people are insane and it's a note taking app, it's very easy simple and quick to use. I love it.
