Wow has G+ taken off. I have to say I believe it to be the best thing that has ever happened for photographers.
I find myself inspired everyday I check in there and I can ask any question and receive feedback 24 hours a day!
If you haven't set up an account, I highly encourage to do so, I don't believe you need an invite any longer, if you do, let me know.
If you are there, please add me to your circles, would love to get to know some of the inspiring photographers I have met here as well. :)
Peace & love
