However, the author of the article mentioned that Google is saying Google+ is THE future of the company. In that case, everyone should be using it. It's not "just another" product.
Just because the author mentioned that doesn't make it true.

The author cites this article, which (ignoring the fact that it is an interview with Google ex-CEO) doesn't even mention Google Plus by name. Personally, I'd say that the author's post demonstrates that Google doesn't think Google Plus is central to the company's future.
Oh, wait.
