I spent two weeks last January trying to reorganize my notes into a traditional folder hierarchy. Every morning I would open my laptop, stare at a tree of nested directories, and feel a quiet dread — the kind that comes from knowing you are building a system you will abandon by spring. That frustration is what led us to remove folders entirely from Fern.
The Filing Cabinet Problem
Folders were designed for physical objects. A document lives in one drawer, on one shelf, in one room. But a meeting note is simultaneously a project update, a decision log, and a reference for three different people. Traditional hierarchies force you to choose a single context, and that choice quietly kills retrieval two months later when you cannot remember which drawer you used.
Supertags solve this by letting a single note carry multiple structured identities. Tag a note with #meeting and it appears in your meeting log. Tag it with #atlas and it joins the project timeline. Tag it with #decision and it surfaces whenever someone searches for past choices. The note does not move — it simply belongs everywhere it should.
