But I’m not here to explain why all your R-rated comments were just shared with your family and friends in Google+ circles. I’m here to explain why you should have those circles. What is Google+ and why should you be on it? Funny you should ask.
Created in 2011, Google+ is a social media data layer rather than a social media platform. The key difference here is that any data you share on your Google+ account is analyzed and used to personalize other Google applications like Search, YouTube recommendations, News etc.. Users can reach the site by URL (plus.google.com), at the top right of any Google page or by the tab on the Google Chrome browser’s opening page. Despite being so easily accessible, about half of Internet users have an account on Google+ and 44% of users are active (being active consists of posting and commenting or +1 other posts).
