Tags vs structure notes
Now that my Zettelkasten has a few notes (around 200), I realize that my tags and structure notes are redundant. I tend to create notes from a structure note, and it becomes a chore to add tags that I pretty much never use. I think this comes done to the fact that you can add more structure in a structure note that in a tag.
For example, I am trying to study probability. I have a structure note for the topic (and a few large notes that can act as sub structure notes), but then, should I just add a "probability" tag to all those notes? A "mathematics" one? This seems redundant and useless.
Is there anything I am missing here? What is your use of tags compared to structure notes?
