I agree to a certain extent. But Google + and the identity service are so closely linked that I am having trouble imagining how they could have called it Google Account since everyone would be wondering what they need Google + for. Which is happening anyway but people haven't figured out the part where Google + is your Google identity yet. Even on, or especially on HN/Youtube.

The ability to comment and talk about stuff is going to permeate all of Google's services. I don't really see how else they could do it.

Maybe if they didn't force you to use your real name then everyone wouldn't be having freak outs?

But Google has not just started using G+ accounts for YT comments, they have mixed G+ shares with YT comments. Now much of what I see below YT videos are G+ shares along the lines of, "hey check out this cool video". That's actually less informative than the average YT comment.
