There is also an option to activate Google Chat for your Google account.
This allows you to put your mom in your "Family" circle, your boss in your "Business" circle and a friend from college in your "Friends" circle. However, making too many becomes cumbersome and may diminish the usefulness of Circles.
If you want to see posts by members of your business network, just click on that circle under the stream.There are also privacy settings you may adjust in the profile.Options include allowing people to email you from a link on your profile and being public, private or somewhere in between using Google Circles (explained below).This content can be anything from a status update to a photo.There are a few differences between the Google Stream and the Facebook News Feed.
