Seems it would be rather easy to use the YouTube API to create a YouTube site that allows anonymous comments. I'm supportive of what Google is trying to do here, because I've found YouTube's comments distasteful in the past. For everyone who is pissed at Google about this, though, why not just create a YouTube (like FixYT.com) that does allow anonymous comments? It wouldn't even take that long, and is probably more likely to address your concerns than than the petitions are, as I doubt that Google is backing down from this one.
