The author might be onto something here. There's definitely a lot to be said for the social pressures of feeling 'in' with company culture, I can see why a limited-history, always-scrolling, continuous stream of group chats would create that pressure.<p>I see an analogue to Snapchat, another wildly popular app (in entirely different settings), where this 'fear-of-missing-out' is also very real, with the equivalent of 'status updates' disappearing in 24 hours, and the default 'picture message' being self-destructive. It incentivizes you to pay attention, and to check up often on everyone you're actually interested in, driving more engagement with the service.
