I've also experience #gplus as a place where I've met many great new people, reconnected with old friends, and have enjoyed my experiences here.
How have you been feeling about being on #googleplus these days? What have you enjoyed the most?
I've been calculating the growth rate of G+ for some time now at a website that I myself host http://plus.miernicki.com and if you would like to plug this data into another application, you can access the raw data (as JSON feeds) from http://plus.miernicki.com/plus and http://plus.miernicki.com/minus
To just say is just about numbers would definitely be doing it a disservice. In the 3+ years I've been here, I've made tons of friends, shared countless stories/photographs, and had interactions with a very diverse group of people... and to that I say, "Here's to the next 2 Billion users!"
#theresnosuchthing as being FORCED to have a Google+/- account.
