Channels decay silently, and the technical cause is rarely the software. The cause is unstated norms — everyone assumes different rules, and assumed rules always lose to typed ones. A one-page charter settles them for years. This chapter sets out the norms that matter, and why they work.
Three norms that do most of the work
- Reply inside the post. Threads keep unrelated topics separable. A flat wall of replies is a grief to search and pure grief to read next week.
- One topic per post. A post is a headline for a small idea, and a busy channel is a fast skim, not a poem.
- Name the ask. “FYI” means no action. “By Friday” means exactly what it claims. Colleagues cannot act on ambiguity that has been shared with them at speed.
In practice
Response-time promises need to be written down in every most-used channel — for instance, “aim for 4 hours on a weekday” or “urgent = @mention the on-call, not everyone”. No one argues with a written time; you will, however, be visited by interpretations otherwise.
Onboarding: norms are learned language
Newcomers calibrate from other people’s behaviours, and the first week of messages is how they learn yours. The cheapest cure is a pinned post carrying the charter, plus one worked example of a well-formed message, visible to everyone. Ask your own question in the open during week one — people copy what they see done, and a leader who asks questions in public licenses an entire team to do the same.
Boundaries at speed
Norms under pressure
House rules earn their keep exactly when work heats up: what belongs in a private chat, what “urgent” means, and whether late-night messages expect an answer. Norms do not usually fail from bad intent — they fail from having never been typed. A team that writes the boundary down before the crunch solves none of this drama in the moment, and therefore gets to keep the drama out of the channel.
House rules are the origin story of every calm channel. Write yours before the noise builds, revisit it annually, and let it preserve the pace of each channel rather than each author’s mood.
