Nobody knew what Google+ was.

'Company A strategy vs. Company B' is not something 'people' think or know about.

That's something for people in the industry to think about.

Ask your mother or father who work in Real Estate and Healthcare what 'Google+' is (back in the day) and they wouldn't really know.

And nobody knew what Wave was. I used it and couldn't understand it, other than it was a means to communicate with other people. Colossal product marketing, usability and communications failure.

As far as I remember I first thought it was some weird exclusive blog platform, that impression only turned into a "complete failure to clone facebook ran by a team of brain dead morons" when they tried to force subscribe everyone to it. It was impressive how Google could completely fail at something, of course Google and Facebook made a few deals to stay of each others turfs behind closed doors so that failure may have been intentional.

Almost. It was Google's attempt at cloning Facebook by cloning Diaspora.
