The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

It leaves no sign of its past self behind When buildings are torn down and rebuilt, the ghost of the old building is often visible in the new one — strangely angled walls and rooms, which make sense only in the context of the space as a living organism. On the web, there are no such restrictions: when a website dies, it leaves no sign of its past self behind. deathwwwarchitecturebuilding
This obsession with permanence I think a lot about the lifecycle of websites. I’m frustrated by so much of the short-term thinking I see in the world today, and the way we think about websites is a part of that: it’s “normal” for them to just go up in smoke as soon as their authors stop paying attention. People switch platforms and providers and break links without a second thought. It pains me to see people build websites with no feeling of obligation to them — when you put something out into the world, it is your responsibility to care for it. At the same time, I wonder if this obsession with permanence is misplaced. care
