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.

Babble and Prune For those who read and listen much more than they speak (guilty), an overly-strict Prune filter is applied to their writing; when these people go to write something of their own, their minds don’t produce thoughts nearly as “coherent, witty or wise as their hyper-developed Prune filter is used to processing”. Hence, my dilemma and an opportunity to break out of this trap. I recognised that if I attempted to write at the quality I was used to reading at, first time every time, my brain would promptly grind to a halt—like trying to brainstorm with a group that laughs at your suggestions. writingcreativity
