This is a WordPress Plugin where you can import.Many of us Google plus members also have our own blogs. Google+ can be a huge traffic drive if you spend time to participate in the community
and add interesting posts to your profile. If you are spending a lot of time finding content and posting it to your stream, there is no reason you should not import some of your content into your blog. Google+ Importer is a WordPress plugin that helps you do just that. (By Panah)
In order to get started, you are going to have to provide this plugin with your own Google+ API. You can sign up for a key here. What’s nice about this plugin is the fact that it lets you import posts under a specific category (posts can be filed under specific authors too).
