Google has launched Google Talk

Google's Web site late Tuesday provided a link to download Google Talk and stated that the software "enables you to call or send instant messages to your friends for free-–anytime, anywhere in the world." Google's messaging program is linked to Google's Web-based email program, Gmail, both of which are in a beta, or test, phase. While Google Talk was expected, some industry observers questioned what innovation Google could add to lure loyal users and their millions of buddies away from established instant-messaging applications.

One advantage to Google Talk could be its ability to connect with users of competing services. Google Talk is based on the Jabber open-source standard, which allows consumers to connect with other messaging systems that work with Jabber, such as Apple Computer's iChat, GAIM, Adium, Trillian Pro and Psi.
