Related notes should create paths, not clutter.
More links is not automatically more useful.
A good related note gives the reader a reason to keep going.
It says:
This thought connects over here.
This question has another angle.
This older note shows where the pattern came from.
That is a path.
Clutter is different.
Clutter adds links because links are available.
The archive should feel deep, not noisy.
Related notes should help someone wander with purpose.
