Example text
While the Napster data is distributed across millions of hard disks, finding that data depends on a central server. com and Napster is smaller than it appears: one centralizes the files, while the other centralizes the addresses of the files. The real genius of Napster is the way it makes participation automatic. By default, any consumer is also a producer of files for the network. Once you download a file, your machine is available to pass along the file to other users. Automatic "pass along" participation decentralizes file storage and network bandwidth, but most importantly, it also distributes the job of building the Napster song database.

Automatic "pass along" participation decentralizes file storage and network bandwidth, but most importantly, it also distributes the job of building the Napster song database. Dan Bricklin has written an excellent essay on this subject, which we've printed in this book as Chapter 4. " Dave's comment highlights why the connection to the open source movement is significant.
If Napster let me get only a few popular songs, once I downloaded those I'd lose interest fast. But what's the root cause? Why are so many songs available? Hint: It has nothing to do with peer-topeer. Peer-to-peer is plumbing, and most people don't care about plumbing. While the "look into other people's computers and copy directly" method has some psychological benefit to people who understand what's going on (as indicated by thinkers such as Tom Matrullo and Dave Winer), I think the peer-to-peer aspects actually get in the way of Napster.
