I don't see any notes. Should they be attacked somehow?

comment Characterize a full functor as a morphism
You are using the concrete function to define those two objects as "the only two categories that the concrete functor takes to the 2-set", correct? Then $J$ must be any given morphism between those categories? This is a great answer, but I would prefer a definition that doesn't take those objects as primitives. Is there a way to define them using their categorical properties? By the way, I'm particularly interested in the case where the categories are preorders, in case that makes it easier.

comment Decisive equivalence of collections of probability measures
I don't understand the question. Are you just asking if there is a name for that relation, or are you looking for a different, but equivalent, formulation?

comment Properties of joint entropy
After you say "then you require" you have a chain of implications, but what you really want are the reverse implications. A quick fix would be to change them all to if and only if.

comment Properties of joint entropy
The answer is great, but the way you used the implication signs disturbs me.
