I've been working with this idea for a while, that it's immutable pagination that makes any written work worthwhile. With it we can spatially reason about it and we commit its location to memory. You can never do that with an infinite scroll.
Maybe a time-based tree structure would improve how we use slack for example.
The problem with growing content is that either the location changes because you either see newest first or you autos roll down to the latest on entry.
Navigation through a time based ToC seems like a compromise but not one I love
Forum pagination locations never change unless a whole bunch of stuff is deleted. Page 0 is always the oldest.
Even with deletion, and traditional pages, you could make pages immutable in several ways. actually creating explicit page objects in the database, saying "page 40 starts at N time and goes until the next page object"
