These blog posts from 104 days ago said that it would no longer be necessary to have a Google+ account to comment / upload / otherwise interact with YouTube "in the coming weeks". It's been almost four months now and I still get prompted to make a G+ account for most of these actions. Is it just me or did they never deliver?
So technically yes, but I imagine very, very few people qualify.
