GTalk has been replaced in Gmail by Hangouts for Google+. Now you can chat with up to 10 friend’s right from your email inbox. In the past, you’d be able to chat with just one other person. This is a huge update for those of you that use your Gmail account for business. You can quickly start a video conference right from that important email. Check out the video demo above to see how things should work. More information about this service can be found here.
