This and TFA hit to the heart of the problem with Google+: Google has willfully refused to acknowledge or understand that singular humans have multiple personas, and that we do not and cannot allow those to mix. Your professional face is not the same as your close-family personal face is not the same as your secret webcomic artist handle is not ... you get the idea.
There are so many mundane variations on that theme, and then there are very serious ones: those seeking support for addiction, as survivors of abuse, or other situations that have social stigma or personal risk attached to them. Some needs are simply private in that way a vulnerable person needs secure anonymity lest the public light itself become a chilling effect, of which health concerns are a common example.
The architecture of Google+ is such that it is inherently inhuman in its disregard for privacy and for applying different "pen names" to the various situations of life.
