- It really should be a ternary selector, not up/down + flag. You should only be able to select one of the three.
- Having both up and down contribute to undimming would actively discourage using disagree as "punishment". It would very likely change how "flag" is used, though the proper use of "flag" is unclear to me right now, as from what I can tell its effect is not visible until the comment is dead. It would clarify the effect between "down" and "flag".
