Three years ago today, Google+ was launched. Since then, reviews of the social media network have been mixed.

The positive column of Google+ includes Google authorship, Google Hangouts, and the Google +1 button.

Your Google+ account helps you claim authorship of your original content. Google Hangouts is a free video chat service on the Google+ platform.

The negative column includes a high volume of forced integration, poor website navigation, and inactive users.
