It's an understandable position. From Google's perspective it may be less about pushing social media and more about uniting a platform. They purchased YouTube and other "separate" techs out there and are not integrating it. That being said, I dislike the rationale that to provide feedback I have to have a Google + Account - especially if I already have a YouTube account. I'm providing feedback - I don't want to share that with anyone in my circles... Unless it's TableTop that's just awesome.
