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"
Best Answer
I got this notification in GMail, while on Google Plus I got a notification those contacts added me back.
It is possibile that this is a new notification type previous versions of the notification counter didn't have support for, and thus "did something" is what they fall back onto.
