A Taxonomy of Communicative Modes

While lurking on the internet, I stumbled across a post from 2019 by @literalbanana on Twitter/X outlining different modes of communication.

It seems both balanced and concise in a way that strikes me as "Wow, now I can't unsee that." I want to share it here.

1. Information transfer along a channel of high shared context
2. Channel maintenance (phatic, e.g. communicating for social function rather than to convey information)
3. Context onboarding (FAQs, lurking)
4. Information transfer along a channel of shared unknown context (alarms, shrieking)

Side-channel leaks? "Every context-rich information channel is simultaneously fighting with every other such channel."
