IT IS STILL BROKEN. On your own channel, YouTube, I was only able to "Load More" comments exactly 17 times before the option disappeared. This only allows access to the latest 360 comments.
On a different popular channel (Klattu42, the "ultimate dog tease" channel) I am only able to click "Load More" exactly 5 times to see the latest 120 comments, which only goes back 3 weeks.
How could this get screwed up? Also, the "Load More" button obviously causes a longer and longer delay with each click, as the page grows beneath it. Would having PAGE NUMBERS be too much like the old style, or just too useful?
It's too early to celebrate about the channel comments. Sorry guys.
