Journal VS Zettelkasten
Journal has a fixed linear structure where you always put information at the end. It's like you're posting information to a Newsfeed on facebook. Append-only.
Zettelkasten is about constantly putting information in the middle.
Creating branches of thought. Also IDs are there too to help it be even more flexible to make it a full graph.
