The new social network Google+ is trying to corner (or catch up, depending on how you see it) on the expansive reach of online communication. The idea revolves (ha!) around their Google+ and their “Circles.” Circles help you organize everyone according to your real-life social connections. Then, you can share relevant content with the right people, and follow content posted by similar people you find interesting. Basically, Circles more closely follow the way you organize your contacts in real life. Circles offer a simple means of organizing one's social network by grouping contacts.
Google is hoping their site will make user feel secure. Their approach to privacy and extensive controls over what you share on the network will put Google+ in a new class of security.
Once you decide to remove someone from a circle, you can drag his or her image out of the circle. No more asking if you want to remove someone or changing friend lists. Google will require the user to use their real name and upload a photo or favorite profile pic. Then the user will be able to include all the information they would like to or not.
You will also be able to control how much of your profile is visible, similar to other sites.
