I initially came here trying to figure out ‘folder’ organization vs using tags(or whatever else might be appropriate)
Given that folders always suffer the problem of being single reference and static hierarchies, I’m not sure what my Vault folder structure should be.
I’m still on the search and the PARA method might be a good baseline reference
One note to be a stickler about syntax, tags can’t have spaces 
#level-1/level-2/level-3 is a valid tag!
