Shhh look what I bought! I grabbed myself a copy of's book What The Plus!
Technically I've already read it as I contributed a chapter (Chapter 11+) to the book along with fellow contributors& . I actually purchased the book because I'm sure it's different from the draft I first read. It's a great resource for people that are looking to use Google+ for their own enjoyment and want to be social butterflies!
Check out http://www.amazon.com/dp/B007HD7HT0 to find it on Amazon, it's under $3 for heavens sake!
