David Gelernter is prognosticating the future of the web in Wired today. He's got a history of being right:
The most important way people are going to make money on the Net is on the model of the electric power utilities or cable TV companies, by providing a service that you are going to pay for monthly. I am going to hire a server to manage all my documents, I am going to throw out my desk and file cabinets, I am not going to care what computer I use, and I will be happy to pay $12.50 a month for an absolutely reliable storage facility. This company stores my documents, supports all sorts of fancy searches, and makes my documents available anywhere.
