As far as I'm aware nearly all social networks require you to join them before people can 'follow' you on them. So I don't see how what you said contradicts my point : if you don't make a G+ account you are going to lose out in organic search ranking.
Your point was to elicit ridicule of Google and Google+. If your point was to instruct authors to share their content by any means and on all platforms, then you should have made that point.
