Even if most communication is async there is a part of "somewhat async" and a part of "mostly sync" communication. And then there is the social aspect of not being alone, but "seeing" that others are working as well. On the semi-async stuff: If I am stuck with a task I probably can grab a coffee and eat a snack or check mails, but I would like to get some feedback soon, while I'm in the state of mind of that task. Else I switch completely to a different task, which has effort to come back on speed on the initial task on e the feedback is there. And if there is some clarification needed, it is good if all parties focus on that topic for a while, till key questions are cleared and everybody is unblocked. Of course it is a balance.
