My follower growth has slowed. The first product page I put on Google+ (a book about Android) got many followers quickly. Same with my personal page. The second time I put up a product page for a book, the response was much attenuated, and my follower growth has been slow and low quality. It wasn't great quality on Facebook either, but it was much faster. Maybe I need to see how well product pages would do on LinkedIn.
They specifically bifurcate the two types of users. There's ~500 million if you count the G+ interactions through youtube and other apps.
Why dont they say how many unique users create a daily post not generated from a app?
We are not talking about adding a youtube comment, uploading a photo with picasa or using the google play store. We are talking about actually using the thing.
