Besides the integration with Google Talk, orkut is about to have other new features. Here's what I found:

orkut SMS

With orkut SMS you can send and receive scraps with your mobile phone as well as other cool stuff. But first you need to register your mobile phone to use orkut.

Photo Tagging

You can tag your friends in photos. To create a photo tag, click and drag the mouse to select a friend. </img> </img> </img> </img>
