I agree with the general thrust of the essay. But, I'm not sure how this part — especially the last sentence — works in practice: yes, abundant affordances provide many opportunities to respond, but if you stop listening before the other person finishes, in order to formulate your response, you miss most of what they said. That seems like a transactional way of communicating. You'll have something to say on your 'turn', but you won't actually be discussing much. Careful listening and actual curiosity about the other person are the keys to conversation, in my experience.
