Choose channels by latency, permanence, and audience. Urgent production incidents may warrant paging, but architectural debates belong in documents with comments. Resist mixing multiple topics in one chat stream; instead, open a focused thread that a newcomer can digest quickly.
Write titles that answer who, what, and when, then keep threads to a single decision or question. Tag stakeholders and link relevant issues. Clear naming turns archives into a reliable library instead of a maze of half-remembered messages buried by time.
Status emojis and profile notes can declare focus time, deep-work blocks, or limited bandwidth. Use them intentionally so colleagues know when not to expect replies. Reactions acknowledge receipt without noise, reducing anxiety while keeping channels readable for people waking up later.
