I have an idea for a horizontal forum to solve this very problem. Soomeday I will work a little more on it. But the idea is that you have horizontal rows formed by every new comment direct to the post. And the subsequent comments of the thread are in this row. This way it is easier to skip to the next comment thread. One thing you lose is the indentation that allows subthread on each thread, but I don't think it is a relevant loss. And the ordening of the rows a mix of chronology and upvotes.
