Jason Kolb discusses the idea that everybody should have a personal server. That server should store all his microcontent, macrocontent and communication. I guess that most people already have such a server, it is their PC. But I guess what jason Kolb means it that this server is connected to the Internet and can be reached from any place, such that the data is present and available at anyplace, anytime. This still can be the PC. Many PC's are now connected to the Internet via broadband and can thus serve as such a personal. But again I do not think that that is what Jason Kolb means. He wants to place the server at some hosting provider for reliability. That would be good idea and we come here in the realm of DLA's. However a DLA is more about publishing than personal hosting. So the question becomes a bit what these personal servers should do? Are they just storage facilities, such as Amazon's S3? or should they be more?
And the question that Jason Kolb does not answer is the integration with the desktop, as he thinks that the desktop is dead. However as long as the desktop offers a much better interface than the web, it is not dead. We should look for an integration between the Internet and the desktop, beyond browsers and classic desktops.
