If it gets bad enough, I'll probably go exclusively on nicovideo. They have more interesting stuff there anyway-- in not-shitty quality most of the time, unlike YouTube, where if there is decent quality, it takes forever to load for me.
Besides, the comment style on nico is so much cooler than YouTube's. Not only that, but the community is less retarded, too (well, from what I can read, at least. Let's hear it for not knowing how to read more than a few kanji~)
