I think an expansion of that subproblem is that “agreement” is determined in more contexts and modalities depending on the context of the comment. Having only one axis for it means the context can be chosen implicitly, which (to my mind) sort of happens anyway. Modes of agreement include truth in the objective sense but also observational (we see the same thing, not quite the same as what model-belief that generates), emotional (we feel the same response), axiological (we think the same actions are good), and salience-based (we both think this model is relevant—this is the one of the cases where fuzziness versus the approval axis might come most into play). In my experience it seems reasonably clear for most comments which axis is “primary” (and I would just avoid indicating/interpreting on the “agreement” axis in case of ambiguity), but maybe that’s an illusion? And separating all of those out would be a much more radical departure from a single-axis karma system, and impose even more complexity (and maybe rigidity?), but it might be worth considering what other ideas are around that.
More narrowly, I think having only the “objective truth” axis as the other axis might be good in some domains but fails badly in a more tangled conversation, and especially fails badly while partial models and observations are being thrown around, and that’s an important part of group rationality in practice.
