I'm surprised they don't just disable comments for viral videos, too.

Now that I think about it, imagine the equivalent of that for other services. For example, imagine if all of Reddit's "default" subreddits (the ones that make up the front page when you're not logged in) had no comments attached to posts. To get comments, you'd have to opt into a community. (Which might very well just be a post-for-post mirror of a "default" community, but with comments enabled.)

Seems like it'd be kind of... nice?
