I'm no pro at Google+, but you have to be signed in to your google account to see it right?
If so, I'm skeptical as to how many people are using this. I've not seen it on sites, and nobody I know who's not a webmaster is signed up into a Google account.
Google+ SEO factors now trump linking as prime algo ingredient.
Now that I really don't believe. Google's serps didn't change that radically, there's not a bunch of new sites at the top of the serps with no links and lots of +1's.
