What's your take on Blogger/G+ comments integration?

(Largely) cross-posted from my Google+ account.  See Alex Chitu's breakdown on Google Operating System for an in-depth look.

I'm very interested and also see what +Dan Jones said about his concern for restricting this to Google+ users:

Only allowing comments from people with Google+ accounts is a terrible idea. I want as much discussion on my blog as possible. I would never want to limit comments to only people who happen to use my favorite social network.
Thank goodness this new commenting system isn't mandatory for Blogger (yet), because the whole idea is awful.

Maybe Google really wants to get people onto G+.  How do you feel about the development?
