Source: 📖 How to Take Smart Notes

Use tags selectively and sparingly

Tags should not be overused within notes. This has the tendency to lead to over-categorisation, which we do not want for the purpose of the slip-box. They should be used very selectively and sparingly as the slip-box is not a tool for archiving but rather a tool for thinking—the links between notes are therefore far more important than tags.
