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
Someone did something in Google+, but what did they do?
google plus;notifications
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.
