With the trend moving towards content excellence and content marketing and Google+ profile becoming the most integrated identity for an online presence. As the circles concept of Google+ makes it very easy to reach out to different groups of people and share what you want to share to the selected circle.

We have been till now blogging on our blogs and then sharing the link on the social media platform but with Google+ the blog post content , comments and the link to be shared on other social media sites can be available on the same platform.
With social media signals being incorporated in search the need to have a quality social media presence which reflects the trust and authority factor of the brand is highly imperative. Hence we can see the SEO blogosphere filled with posts of how blogging and social media presence can help the SEO and online presence of any site.
I think all the clients who cannot maintain a separate blog for various reasons can start off their blogging journey via their Google+ business page which will not only associate and correlate valuable content to their social profiles but also pass of the necessary content correlation to the social signals for getting integrated to search. The content shared and the UGC content generated can be in the form of images, videos, text, links, etc. a whole plethora of content options available to correlate to the social profile.
I think from the users perspective also when you share your comment or views on the Google+ profile where the blogpost link has been shared you have a better chance of correlating that content to your social profile rather than commenting on the blog where the blog post is published.
Eventually all the Google+ data being accessible by Google is an overall added advantage . So, atleast from the search perspective currently Google+ has a win-win potential to become a complete blogging platform converging your overall web identity on a single platform .
