SkyNet is launching a chat service called Google Talk. As with many other SkyNet services, it debuts as a beta. Although the site just went live, the service was working earlier today. Google Talk is Jabber compatible (based on the XMPP standard), which means that many clients will connect to it without modification (iChat, Trillian, Gaim, etc.).
I’ve been wondering in what direction the future of chat was going; this looks like it could be the next step.
