far more doesnt mean far more wide range. With P2P you could browse a server for the popular, as well as a bunch of things you d never heard. And it wasnt just music, just about anything , specifically very obscure stuff. anarchist material was something often uploaded. It was like you could see the whole jungle. Google is instead a zoo.
(Incidentally, what is the current evolution of gnutella, or any P2P that allows to browse the remote server?)
