So I went on Robbaz' channel to watch some manly vids.. and I come to this wtf? Why does Youtube insist on changing the channel layout all the time? I preferred it when the channels were more personal, this just sucks.

Error occurred with you video, however I think I know what you're talking about. It seems to happen with really popular channels, and it's kind of abrupt at first, but I got used to it. However I still find the channels with personal boxes for likes, comments, videos, etc to be my favorite. That was changed years ago, however.
