Subject: Re: Favorites, unread posts view
The previous system remembered the last post that you clicked on, which was then the first post shown before the unread posts. From there one could always hit the 'previous' link, or change a post to threaded to read back in the discussion.
I believe many people left the boards in unthreaded, and skipped through the posts one by one, or opened only the ones they found interesting or that had enough recs.
Can't speak for others, but I usually clicked on the last post on purpose to mark everything as read (or clicked on 'mark all read' on the Favourites page), to start the next session with a clean slate.
