Sort of a body of D&D discussion Common Law...?
Sounds like a lot of work.
I'm thinking of some of the particularly thorny ones - that are often thorny because they aren't arguing much about the toppings and crusts and cheeses, but get more into the pizza maker, pizza server, and pizza eater and how the choices of restaurant decor tie into non-pizza IRL things and make it an unpleasant experience for some eaters. Or how slight changes might alleviate that, and why we should all worry that our pizzerias are welcoming.
I certainly wouldn't want to do one about NY vs. Chicago vs Detroit pizza and their merits, and which one sold out or not, and which one is untrue to its roots, and which one could just as well be a burrito stand.
