Here is a summary of the article in one paragraph: The author proposes a simple rule for video calls: if there are five or fewer people on the call, don't mute yourself; if there are six or more, mute unless you're the person currently talking. This rule aims to balance natural conversation flow with the need for non-verbal cues and clarity in large meetings. Exceptions include when someone is presenting, when there's a distracting noise nearby, when eating, interrupted by something, or when leaving video on due to bad internet connection, being in transit, or not planning to speak. The author also suggests always leaving camera on unless absolutely necessary, as it helps create a sense of presence and makes meetings smoother.
