No, that was certainly not the case. I got the error message the first time I tried to post it, but now I can see that my comment later posted here anyway.
Glitches aside, as other people have already mentioned, the order of comments within threads makes no sense. While it was useful to highlight in some way what the latest comment was, especially on longer threads, to order the comments from most recent to oldest makes no sense.
I mean then the conversation makes no sense at all. You cannot follow the flow of it. It's really confusing and non sensical. It's like reading a newspaper article paragraph by paragraph, but starting with the last one and moving backwards. On some threads, it really does your head in!
