In terms of architecting content collections, I'm kinda opinionated. I think it should be:
theme > author > medium
web kinda likes to force the exact opposite order though
LBRY allows slicing of content metadata among all logically possible permutations, designed in a way that metadata is not in custody of the company (or any one party), freeing the anchor to medium or one design
