One of the biggest advantages of Google+ Circles is that you can create distinct groups of people in your social network so as to allow you to share specific updates or information with only those people rather than your entire social network.
Google+ circles are great for targeting posts to specific groups. I have a geek group, photography group, seo group, marketing and so on. It really helps, especially if you have a large number of people in your circles.
Google+ circles are just like groups. You can categorize your followers under different groups names such as family, friends, colleagues, partners, etc. It helps a lot while searching and performing mass actions.
when people follow you... do they still get to see content meant for that circle if you haven't added them to the circle yet?
Google+ (pronounced and sometimes written as Google Plus, sometimes abbreviated as G+) is a multilingual social networking and identity service[SUP][/SUP][SUP][/SUP] owned and operated by Google Inc. It was launched on June 28, 2011.[SUP][/SUP] As of December 2012, it has a total of 500 million registered users of whom 235 million are active on a monthly basis.[SUP][/SUP] Unlike other conventional social networks which are generally accessed through a single website, Google has described Google+ as a "social layer" consisting of not just a single site, but rather an overarching "layer" which covers many of its online properties[SUP][/SUP] .

Circle is a good feature in Google+. You can add and remove and change your circle. You can share things with the people of your circle.
The best part about the G+ circles is that you can segment the people as much as you want. You can have different circles for different niches, how you met people etc. Also people can be in more than one group so it makes it even easier to segment however you see fit.
