I looked up some history behind Google+ on Wikipedia and it looks like Vic Gundotra was behind that (footnotes removed).
> His responsibilities as Vice-President of Social included Google's social networking and identity service, Google+. He is widely believed to be the man behind Google+, and was responsible for the controversial removal of social features from Google Reader. Apart from Google+, he is widely credited for his contributions to early versions of Google Maps (application) and Google I/O.
For it's time it was kind of the proto "news feed" for my group of friends.
It seems there's something missing from BigCo's understanding of how social networks operate.
Among my thoughts: the group of people really discussing things online just isn't that big.
Reader was far more significant than Google realised.

Both Enge and I address both the definition of "active" and of "invisible" non-public activity.
1. We're limited to directly observable public actvity. Given the sitemaps providing a population of profiles to sample, that means looking at actual public posts. Anything else would be Making Shit Up, which I prefer not to do.
2. It's possible get some sense of non-public activity by looking at followers and views for profiles with and without public activity. Evidence is that profiles without public posts have about 4.3% of the activity of those with. That gives roughly 4% of the total G+ userbase, or about 95 million users.
Again: showing activity at any time. That about doubles the active users count in total. (112 million + 95 million). It doesn't speak to recent activity, though.
My initial G+ "public activity" analysis: https://ello.co/dredmorbius/post/nAya9WqdemIoVuVWVOYQUQ
Follow-up "active" public sharing accounts vs. "inactive" non-public-sharing accounts https://plus.google.com/u/0/104092656004159577193/posts/RhnK...
Not as fancy as some of the commercial offerings, but I never need to worry about it getting killed off.
I couldn't stand feedlys interface, and theoldreader is good enough.
