@trwnh @silverpill @erincandescent @julian oh, yes, that's true, if you do "volatile paging" (last 20 pages).
If you have reified pages (item goes in one page and stays there), once the pages are full, they don't change (except for `Remove` activities).
Don't do volatile paging.
If you use reified pages, an add to a reverse-chron collection will typically have changes to `first` and the Collection itself.

If you have bidirectional links (`first` and `last`) you can have stable collections with rev-chron or forward-chron. So, fair point.

@evan @silverpill @erincandescent @julian Yeah, my point is that it seems almost entirely conventional whether to have "reverse" mean first.next.next... or last.prev.prev... -- and I favor the latter approach because it makes more sense imo, no double-inversion ("reverse-reverse chron", anyone?)

@trwnh @silverpill @erincandescent @julian Except for most interfaces, your first page is the current stuff, and you go back in time to find earlier stuff.
-
@trwnh @evan @silverpill @julian personally I don't necessarily think you should do reified pages in most cases; but I do think you should do stable cursors; that is, you can traverse a collection as slowly as you wish and you'll get a coherent view.
Bonus points if the most recent page of the collection has a next link that points to an empty page where newer objects will appear -

@evan @silverpill @erincandescent @julian This is what I meant by "conventional". On a forum thread, you generally read forward. On social media like Twitter, there is a heavy bias toward going reverse. And some interfaces even let you choose ascending or descending order.

Evan's poll about Activitypub doesn't show on NodeBB instance, why is that?
-
There's probably a FEP that needs to exist explaining how polls on Mastodon even work, plus how they should work (it's not what you might expect)
