In the last couple of days, three cstheory users added me in their Google Plus circles. I don't mind to have these people in my circles, I was just wondering: is there some automatic thing that makes this happens?
I made a circle of cstheory folks and shared it with the people in that circle. That is probably where your additions are coming from. You should be able to see my share of the circle in your stream. I don't plan to share the circle publicly at this time, and if you want to be removed, let me know and I will make sure to never share you in any public circle.
Also, to stackers that want to be added to the cstheory circle, let me know and I will add you.
