*nods* Right. All the full names that one is entitled to doesn't necessarily equal preferred form of address, and furthermore preferred form of address can vary based on audience. I'd be formally addressed as the Reverend Lunatic, but close friends (and all of #dreamwidth IRC) should call me Azz. Neither of these names are especially an intuitive contraction of "Azure Lunatic", and while I'm the same name up and down most parts of the internet, I have to adjust my name as it is displayed to various portions simply so I don't get addressed in the wrong way (as no one but Betty may call me AL, but chat forums do have a tendency to shorten names). So one of the things that G+ could have done right would be to allow one to have a different immediately-displayed name to each circle so they could call me correctly, whether or not they saw my full name as displayed on my profile.
