I've called TVTropes the great index of all human behavior before, so this seems somewhat like an honorific.

Everything is connected, so much behavior is cross-culturally human, and TVTropes in particular is a great uniter of plot, a collector of how wide & differently a common theme or plot can be created. It links together so many moving pictures, identifies underlying factors.

I haven't particular thought of Z as so all-encompassing, so unifying, before.

LOL, which is _why_ – after learning about plots and tropes last week here on HN – I had to _naturally_ create "Plotto for Obsidian"[^1]. (It's basically all of Plotto exploded into navigatable markdown files for faster discovery.)
