What actually happened when the Google+ notification says a contact "did something"?
Here's a screenshot of the notification I see in Gmail about G+ activity:
Rahul yadav added you on Google+.
Gaurav Tripathi & Nilesh did something.
But what did the contacts on the second line actually do? Does this wording mean anything in particular?
Another example:
Edit : Now, That notification is modified as follows.
I assume
"They did something = They added me into their circles"
