Why add video?
With changing technology, we can now see and talk to anyone around the world using the video chat. Putting a face with a voice brings a human touch back to communication. With high speed internet and a webcam, we can see someone who is half-way around the world. Due to this, the world is becoming smaller. But the real benefit from video chat is the improved communication that comes from seeing facial expressions of friend or relative. You can't get that from e-mail. And even the telephone lacks the personal touch of video chat.
