Google+ Feature Suggestion: Rings/Spheres/Super-Circles

[Estimated Reading Time: 2 minutes] A tenuous link to Delphi I accept, but a Google+ suggestion occurred to me, arising from my Delphi-oriented use of it. A potential problem I am seeing already on Google+ is where I get a notification that “So-And-So” has added me to their circles. In some cases I don’t know this person, but they have added me because *they* know they share a common interest with me. I cannot see that they have this interest, because I am not told which of their circles they added me to or why – and I should not see this. I appreciate the privacy this affords me when on the other side of the equation.
