In a move to unify its products and services, Google (NASDAQ: GOOGL ) has integrated Google+ into Blogger. Currently, the integration is optional.
Blogger users now have the option to enable Google+ commenting through the Blogger dashboard. When Google+ users discuss a blog post, the Blogger user will see the comments and replies on his or her blog.
On the Google+ side, users can comment publicly or privately. In addition, when browsing a blog's comments, Google+ users can view all the comments, just the top comments, or those from people specifically in their Google+ circles. Google hopes that by allowing users to see the comments they have permission to read, they'll encourage more meaningful sharing -- thereby driving greater blog traffic and, in turn, perhaps increasing usage of the Google+ platform.
According to Mashable.com, Google+ has more than 500 million members.
