I think we've known this for some time as we've seen each Google property requiring G+.

This story from the WSJ is a little late for us, but for the uninitiated it might make some of them think.

Google Inc. is challenging Facebook Inc. by using a controversial tactic: requiring people to use the Google+ social network.

Google+ is a Facebook rival and one of the company's most important recent initiatives as it tries to snag more online advertising dollars. The impetus comes from the top. Google Chief Executive Larry Page has sought more aggressive measures to get people to use Google+, two people familiar with the matter say. Google created Google+ in large part to prevent Facebook from dominating the social-networking business.WSJ: There's No Avoiding Google+ [online.wsj.com]
