YouTube comments (aside from being a cavalcade of human stupidity) don't even work right. Threads don't work, with replies appearing in random locations rather than indented under the originals (but sometimes they do inexplicably appear correctly). Page breaks are totally wrong, with the same comments appearing on the next page but many of them missing. Really, why even bother. YouTube is a failure of basic design and Google, with all their resources, hasn't been able to field a competent layout. That's pathetic.
