Pladeo (ex InCircles), the chat widget that you can embed on your website, is now also available for Facebook. Put it on your profile, and converse in real time with your Facebook buddies. Features include private messaging and user blocking, as well as something called group traversal which enables a group of Facebook users to have a private chat. The widget also displays popular chat pages.
