I'm still convinced that Google's insistence on funneling all activity from their services into Google+ accounts (even in cases where it clearly doesn't make sense) is being done solely so that Google can go back to their shareholders and report a large amount of "growth" in their social platform. They don't seem to have any end game or plan beyond merely pumping up the numbers as high as possible. Maybe they are just aiming for the day when they can claim Google+ has more members than Facebook?
