Motivation for the étale topology over other possibilities
@DustinClause: do you mean "contractible" in the usual sense in the analytic topology, or in some specific more abstract sense?

Continuous relations?
Ok, thank you for the explanations!

Continuous relations?
Ok, so in the case of the counting measure you have an underlying (set theoretic) relation $R\subseteq X\times Y$. But what about more general measures?

Continuous relations?
Maybe I've missed the point of the definition, but isn't it a notion of "measurable relation between measurable subsets" ($R\subseteq P(X)\times P(Y)$) rather than just a "measuranle relation between elements" ($R\subseteq X\times Y$)?

When is a holomorphic submersion with isomorphic fibers locally trivial?
@Andrea: take a nonZariskilocallytrivial (locally isotrivial) projective fibration; then, by FG, it's locally (in the eucliden topology) analytically trivial. Or did you mean an explicit example?

Why is Set, and not Rel, so ubiquitous in mathematics?
2. Could you also give some reference to the literature on this topic (if there is any)

1. Why is not the usul notion of composition od reltions enough do define "commutativity" of digrams in Rel?

Probability over a plane
Ok.. so I'm surely missing something. I would naively think that the probability that a polynomial has a complex root is always $1$ due to the fundamental theorem of algebra...
