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.

Reverse chronology bias Once you’ve had a taste of effortless updates, it’s awfully hard to back to manual everything. So they didn’t. And neither did thousands of their peers. It just simply wasn’t worth it. The inertia was too strong. The old web, the cool web, the weird web, the hand-organized web… died. And the damn reverse chronology bias — once called into creation, it hungers eternally — sought its next victim. Myspace. Facebook. Twitter. Instagram. Pinterest, of all things. Today these social publishing tools are beginning to buck reverse chronological sort; they’re introducing algorithm sort, to surface content not by time posted but by popularity, or expected interactions, based on individual and group history. There is even less control than ever before. There are no more quirky homepages. There are no more amateur research librarians. All thanks to a quirky bit of software produced to alleviate the pain of a tiny subset of a very small audience. That’s not cool at all.
