Very good, somehow hadn't seen this yet. Thanks! If all comments on HN were disagreements, this could be an interesting alternative to the simple karma score of a comment. Better yet, f we could tease the concepts of each level away from the disagreement element, we could have an interesting way of classifying comments. Maybe a Conversational Hierarchy: CH0 - Attack on a person CH1 - Statement concerning a person CH2 - Statement concerning a text CH3 - Statement concerning a point made CH4 - Reasoning/facts concerning a point made CH5 - Reasoned response to a point made CH6 - Reasoned response to the central point 5 and 6 could use a bit of beefing up, but you get the idea. They could each have karma scores assigned to them (negative for 0-2, neutral for 3, positive for 4-6) and the classification with the most votes wins. The "CH" appended to the beginning of the number makes it so noobs would be likely to the time to learn what they mean. The UI for this would have to be dead simple, maybe a dropdown. Thoughts?
