**DON'T PANIC** is all-caps is an order - that is a rule. In the Hitchhiker Lore I'm evolving there are a small number of such rules that govern behviour of Hitchhikers.
The rule I have thought about more is NO SPITTING. That is partly simply because it is in the Hitchhikers' Manifesto, and partly because it troubled me. This thought led me to how we might be interested in enforcing such laws within the community in a playful and humourous way, which eventurally led me back to the Vogons as originally considered.
# Stress
The utility I can see in this word is related to techniques hitchhikers are advised to learn around reducing stress. Extending this thought we are talking Mental Health and Well Being.
I can imagine a dashboard, with an over-elaborate dashboard monitoring different emotional levels. Elements of this dashboard can be used individually to monitor aspects of a dialogue - or combined.
It would be something an Empath would specialise in. A tool they help craft, and use.
# Temperature When the temperature of an argument or conversation get's too hot - we can Throw in a Towel.
# Narrative I see a narrative connection to the Improbability Drive, where when earlier warning fail to reduce stress, we can press the button and call in help - this is fertile ground for the Hitchhiker Timebank. You press the button and get a massage :)
Another aspect is the realisation of GPP's as annoyingly Caring Robots. Training an AI for sentiment analysis - or simply using an existing one then lining it's output to one of our GPP's is a practical project which is funny / sad / serious.
