This answer is long, complicated, Kas would call it both philosophical and snobby, and I'm not sure you're in a good position to guess all the meanings I used. But I promise the same symbol means the same thing every time:
It sort of has three clauses; if you want, I can break it up into those for you.
People who form their own opinions instead of relying on those of others are more likely to be good at reading it? Explains why I'm kind of terrible, I suppose.
same question different querent different question every question different answer its-own answer alethiometer every question its-own answer
Or more readably: The same question from a different asker is a different question; every question has its own answer; the alethiometer gives every question its own answer.
This is a slightly philosophical-and-snobby way of saying that it can be more or less cooperative with different askers, but doesn't always, and doesn't see anything wrong with it.
Hm... does that mean other people should copy some of my questions? :P
Anyway, alethiometer, that time when someone asked if Elspeth could feed harpies, was your phrasing of the answer ("truth speak speak truth") mocking for being unable to figure it out easily, or a pun, or what?
