Doc Searls and David Weinberger: World of Ends. I'm still having trouble seeing the internet as a hollow sphere - it's only a world of ends if all the bits pass through the middle, where there's plenty of opportunities for them to be messed around with. As they wrote, "of course, when every end is connected, each to each and each to all, the ends aren't endpoints at all". If the bits all pass around the surface then it's more a World of Nodes. It's inspirational writing, nevertheless.
The companies whose value came from distributing content in ways the market no longer wants - can you hear us Recording Industry? - can stop thinking that bits are like really lightweight atoms. You are never going to prevent us from copying the bits we want. Instead, why not give us some reasons to prefer buying music from you? Hell, we might even help you sell your stuff if you asked us to.
