It give me one less site I need to check. Going to facebook.com is psychologically saying "I want to waste time". Going to gmail.com is saying "I plan to be productive" (not always, but often so). G+ brings social out of the time-wasting world and into the productive world. Now with Circles I can post a programming question to my "Hackers Circle". I can ask my fellow engineering students about the latest homework assignment. I could ask my "Coworkers" Circle if anyone can cover my shift. Facebook is entertainment. Google+ is productivity. Yammer is dead in the water when G+ for Google Apps comes out. They aren't apples to oranges, G+ and Facebook, but perhaps Gala to Granny Smith. A great snack and a great pie. They can substitute for each other if needed, but each do far better in their designed task.
