Q:

Publish Wordpress posts in Google plus?

I need a WP plugin that updates my google+ when I write a new blog post. I want something automatic that doesn#t require to +1 the  blog post.

Have a look here: http://en.forums.wordpress.com/topic/sharing-posts-to-google-1

Google+ has specifically disallowed robo-posting. They want to keep
  the  quality of interaction high and so if you can't be bothered to
  manually  paste the link, they don't want you posting on Google+.

But it seems that there is a script: http://www.nextscripts.com/google-plus-automated-posting
