That is very true to me as well, in my head things are organized in a hierarchy of concepts. The nice thing about tags is that it allows you to store a note below multiple tags like in my case a note about something I did with Python at work, tagged with #work, #work/project_name but also with #python.

I use a plugin called Tag Wrangler to show my tags as a tree like folders (it interprets the "/" as a parent directory).

This allows me to keep a note below multiple tags which I think is useful, at least for my own usecase.
