Google is making it even easier to chat with people you have relationships with. The search engine recently added another feature to Google+; you can now use Google Chat to talk to anyone in your Circles who has added you to their Circles. Prior to this new feature, users would have needed to know the person’s email address before adding them on Chat.
When you’re not using Google+, you’ll still be able to use Chat to talk to people in your Circles using other Google products like Gmail, Google Talk, iGoogle, Orkut and 3rd party apps. One other change to Google Chat is that instead of displaying all of your contacts in your Google+ Chat list, Google will be displaying contacts from your most recent conversations that are online at that moment.
