We discuss this sh*t in every other thread anyway. :" I want to see comments disabled on YouTube too, I guess.
That would probably be the end of YouTube. When the uploader gets comments, he should go through and delete the bad ones. Thats what I do.
The comments are a little better with non music related videos. I never really comment on there so I wouldn't care if they disabled them. But as Hawk was saying, plenty of people wouldn't be too happy about it.
