I actually agree with author (despite his going into a rant in the latter part of the article) about the horribleness of needing a Google+ account to interact with most of Google's services these days (I'm wondering if any clueless fool in their marketing/sales dept. has suggested G+ login for search yet...), but I actually quite like Google+ .
It's, IMHO, miles in front of the competition in regards to large communities, but, admittedly, fails on the actual social stuff (friends, family etc.). But, as I see it, the only reason they fail at this is due to the overwhelming dominance of Facebook.
I now only use FB for communication with overseas (and far away, easy if you're in Australia) friends. Most of my other online community social behaviour is done through G+
Just my 2 cents (with inflation)
