Google is launching a new service called Lively, a browser based virtual world add-on that lets users create and customize avatars and worlds, interact with other users, and generally have a richer social interaction than is offered by GTalk today.
This isn’t yet a full Second Life competitor. There’s no single world, for example, where users can move around. But it’s easy to see Google evolving this into a single online world. And then, of course, selling advertising into it.
