Is time up for Google Plus? part deux

Now, since posting that last post, I've had 3 people add me to Google Plus.

Perhaps
(1) that last blog posting reminded people that--"oh yes, there is that thing called Google Plus. Hadn't thought about that for a long time now. Maybe I should get on there and add EconEric"
(2) My blog is already becoming so influential that those people, super motivated to keep Google Plus alive, added me out of the hope that it lead me to rescind the last post, thus imbuing Google with new life.
(3) It was just randomness that my posting was shortly followed by 3 people adding me.
(4) Some combination of the above.

If you know the answer (e.g., you were one of those people who added me), please comment.
