Completely agree. I think to really show the best comments in a thread, comments should be weighted higher based on how recent they were made. At the same time though, you don't want to weight them too highly and flood the top comments with new, less notable comments because that would seriously deteriorate the quality of the top comments section. I find HN strikes a really good balance here, occasionally putting new comments at the very top, but not enough to flood the top comments. It's much better than Reddit at least. HN also seems to give additional weight based on the length of the comment which filters out many of the joke/quippy comments and gives preference to comments which add a lot to the discussion.
