I have personally had a great experience using Google Plus. I am just about to reach 1000 people who have been nice enough to circle me, and I have to say the quality of engagement has been much better. I like to have intelligent conversations, and Google Plus is a great place to have them. The functionality with such things as Hangout’s, along with the importance of social signals playing an increasingly more important role in search makes Google Plus a must for any serious business today. This is a great article on the social network.
From the article:
While its 2011 launch debut was easily forgotten, Google+ usage has quietly but steadily been growing. So much so, in fact, that usage of the site now surpasses both LinkedIn and Twitter, with over 343 million users and 34% of all social logins, according to a recent study commissioned by Janrain. Google+ now seems more poised than any other social media platform to dethrone Facebook in terms of social sharing.
