Met another photographer at a Hiroshima remembrance event. He wanted to see the photos I came up with. When I suggested G+ he exclaimed "Come on, man! Nobody uses that! Do you work at Google?".
It is hard to argue that most posts I see these days are either from Googlers or people that have amassed large enough followings that they aren't willing to give up on it.
Ouch G+ ...looks like Emerald Sea is becoming Empty Sea after all.
