Thanks for sharing. When I was at the Learn with Google seminar the other day they had a session that focused on Google+. A few of the takeaways I got from that session were to:
1. Make sure and use the +1 because content you +1 and share gets index in the Google search engine. 2. Verify and link your Google+ business page with your website. This creates a rich snippet in the SERPs and results in more clickthroughs to your site. 3. Verify your Authorship. This also creates a rich snippet in the SERPs for content you author and results in more clickthroughs.
