Google have announced their Google Lively vitual world, available through a browser plugin via Firefox and Internet Explorer. Unlike Second Life it is not a single world but splits off different worlds into separate rooms. Using a Google account you can create avatars and interact with others as in Second Life. You can YouTube clips on virtual creens and share photos. Opinions vary as to its quality and where it is leading. See article in ReadWriteWeb, where one of the comments suggests they are aiming at the educational market. As John Major used to say "It's too early to say : we shall have to wait and see".
