After writing this post I reflected a bit more on types of conversations, and made a little graphic to illustrate my transportation metaphor for the internet: Some are walking, some jogging, some biking — traveling independently at varying speeds low enough to pay attention and stop to interact. Some are traveling at high speeds loudly polluting; they interact with others by honking, crashing, or running over. It is pointless for a pedestrian to converse with the blare of a car horn.
