I came to say the same thing. Also, nobody mentioned the "scrolling window" effect on the images behind the headings. One problem is that it doesn't show up with paging (Page keys or scroll wheel), only with smaller scrolling increments. As as counter-example, I continue to be baffled by expired pages here on HN. The parent comment is "below the fold" so I clicked on more comments, read a dozen comments, clicked on the AirBnB link, and by then--about 5 minutes, the Reply button (after typing in my comment, not the reply link below the parent) was expired. I had to back up to the first page of comments, click on more comments again, and then I was able to submit my reply.
