The Google-Plusification of Blogger is proceeding, with Google now making it possible to immediately create a post on a Google+ page for any post made on a Blogger blog. This raises the spectre of blogs roboposting and filling Google+ the way it happens on Twitter. However, it's quite convenient to automate some of your social media interaction. This is a new feature, and follows a move a few months to use Google+ for comments on a Blogger post.
It means that Google is giving Blogger blog owners the possibility to use Google+ for the community of commenters around the blog.
