Google+ Comments now available to your Blogger blog: process and stakes
Henceforth once you've enabled the feature through your Blogger Dashboard,
you'll be able to view your blog and Google+ comments, all in one place
This means see activity from direct visitors, and from people talking about
your content on Google+. And help readers comment and connect with their
circles. This means your blog readers will now have the option to comment publicly
or privately to their circles on Google+. And when they're browsing blog
comments, they can view all of them.
