According to this article, Google+ has nearly 2.5 billion (with a B) users. That’s about as many users as Facebook. However only about 10 percent of the total number of accounts have ever made a public post. What’s worse it the fact that it’s estimate there are only about 6 and a half active users who engage regularly.
Due to the nature of Google+, anyone who has ever used an email account provided by Google now has a Google+ account. Many of these people don’t even know they have a Google+ account.
So here is the question: Is Google+ suffering a slow and painful death? Personally, I would say that it was never alive. I don’t know anyone who as activity engaged on Google+. Is Google+ useful? It certainly could be. But ultimately the features offered on Google+ are already available on platforms with larger bases on users who already understand those competing platforms.
