On viscosity: I was thinking of adding “thick” and “thin” as options, but those would be sort of orthogonal to the other options.

thick and thin would at least be less verbose than my suggestion... :-)

I think orthogonal is fine. It forces a kind of prioritization when one has only one vote.

...the majority is always wrong, and always the last to know about it...
Insanity: Doing the same thing over and over again and expecting different results...

You've got my vote, even if that's not the vote i would make. (I do not mean that as a saucy comment.)
