Looks like the Google guys have added a chat function to the new iGoogle interface. Looks kinda slick.
Announced in April, the new version of iGoogle that brings social applications is tested in a small number of randomly selected Google accounts.
The new iGoogle places the tabs on the left-hand side of the page and you can expand the tabs to see the list of gadgets and status information, like the number of unread Gmail messages. There’s a new chat feature borrowed from Gmail that lets you chat with your contacts while visiting iGoogle – that means iGoogle gets a sense of presence because you’ll know when your contacts are online. Since the chat feature will be enabled by default, it’s obvious that Google will be able to add options for sharing items and discussing posts with the contacts that are online.
