From the article: 

"To organize the people you follow, put them into a circle (like a list). The names of your circles aren’t public, so it’s okay if you put me in the 'loudmouth' circle. I find that organizing these early helps you decide where you want to focus your attention, and sometimes, lets you send info to a limited list of people (though as a marketer, I rarely want to limit my posts to a small amount of people.)

Post to 'Public' anything you want to share with the world at large, and/or anything you want Google (the search engine) to index."
