 It's described as a "writing instrument" because it's not so much about the presentation or even the web format. While that's the medium for this particular implementation, you can notice en serves its raw data in both TOML and JSON. It's first and foremost about mapping out and structuring written thoughts.
 
 Because en is defined in simple configuration files, you can add new pages easily from a few lines and start connecting them. Instead of having to create a dedicated file or resource for each new entry you find deserving of observation, with its own beginning and end, its own "I'm empty, fill me to completion" demeanor, you can stay in the flow of your sprawling thoughts.
