Many of the old posts have unthreaded comments. So maybe it would be good to allow an option to sort comments "oldest first", since this is the most natural way of reading unthreaded comments? In fact, maybe it should be the default comment sorting for such old posts? I seem to recall that this was the case on the old LW site even though newer posts there had comments sorted by karma.
Also, it is a little awkward that the karma on old comments is (old upvote/downvote count, with each vote worth 1 point) + (new upvote/downvote count, with vote weight determined by user karma). It means that when I upvote an old comment it suddenly jumps e.g. from 1 to 4 karma, higher than anything around it. Though I don't know if there is anything reasonable to do about this.
I also noticed this today for the first time. This is not intentional, and I am not really sure what's causing it. We will have to look into that.
