As a new user to Google Plus you will experience a social network environment like no other.
The learning experience will be a learning curve for anyone who has been using Facebook. Like most Google applications once you start using it, you will realize what a simple and basic application it is. This is not to say that it won’t be a frustration to you, as you must relearn a new layout and format. However the ease of use once you start to understand it will be a welcome change.
Give it a chance and overall I think you will be impressed.
