David Amerland already very eloquently said much of what I would have said in response.
It's hard to know who this post is aimed at, whether "recreational" social media users or to business/marketing users, but if the latter (and that is certainly the audience of Social Media Today), then this post sadly reflects why most social media "experts" miss the boat (and short change their clients) on Google+: they live in a social media silo and don't really understand search marketing.
The key to understanding the incredible marketing power of Google+ is to realize that Google has not designed it as "just another social network." It really can't be compared apples to apples with Facebook, for example. Sure Facebook has much larger numbers of active users, but can your business actually reach a lot of those users? All reports are that it is becoming more and more difficult (unless you're willing to fork over lots of money to Facebook).
With Google+, on the other hand, I've been building effective strategies with my clients that dramatically affect their overall search presence, the ability to show up for more and more people who are actively searching for their product or service, but would never find them on Facebook or Twitter. Because I'm a social media consultant who understands SEO, I know the incredible power of buidling an active Google+ network that sends our ripples of influence and search-boosting power far beyond the posting pages of Google+.
