Hey, @dragosroua.
Never was a fan of Google+, mostly because I didn't really understand it. What little I tried to use it for was not all that intuitive in my opinion.
The problem with any social media platform, including the one attached to STEEM, is you need an active user base. If most of the people you know are on one, and you're on the other, outside of getting them to come to you, you will eventually go to them.
I don't really believe Google had a definitive roadmap or plan for Google+, at least not how it worked into it's overall corporate plan. If it was ever intended to become a big thing, it doesn't seem like the resources were poured into it for such a thing to happen.
Which kind of sums up what Google does outside of its work on its search engine. It has many holdings and a lot of tech at its disposal, but yet I don't think of it in the same breath as Microsoft, Apple, or even some major open source projects. And yet, there it is, trying to compete on different levels and in different ways, with all of those, plus Amazon and Facebook.
It just seems like Google wants to get into different things, but doesn't really have a coherent way of doing that. Google+ is yet another casualty of what seems to me to be a lack of cohesion.
The search engine, though—they're crystal clear on that. The rest seems like expensive hobbies, and if something is lucky enough to stick, they might continue with it.
