I’d say among those five base rules, the most important one is this one:
In other words: make empathy the goal. And I’d say that the face-to-face situation tends to support that goal in a natural way because of the of the multimodality (richness) of the communication and the availability of multiple synchronous feedback channels. So my question would be: how do you do that online?
