Google(plus) is like the new Facebook. It has new and different features, like circles. Circles lets you segregate your friends, family, business associates, etc so that your postings can be sent to one or more groups, rather than everyone sees all. It reached 50 million subscribers in 88 days. Facebook took two years to reach that number. Also, since Google+ has been open to the public, it has been adding about two million new users a day.
