I mean while this is a flippant response, this does highlight something that doesn't really exist at the moment: second order derivative lists. You make a list and then I prioritise and filter your list. Making a list of your top 100 books implicitly rejects all other books. Me taking your list of 100 books and rejecting a load with justification gives a lot more information about what I value in the books and, moreover, which of your values I disagree with. We kind of have this with comment trees but it will often be the case that someone publishes a list (e.g. all of the episodes of Black Mirror in order of preference or all Studio Ghibli films in order of preference) and then the comments will take issue with the inclusion of certain items, exclusion of certain items or the placement of certain items. What you rarely get is the commentator publishing their own version of the list and what you never get is the commentator creating a completely derivative list.
