TekhneMakre comments on Six (and a half) intuitions for KL divergence

[TekhneMakre]

The arguments in the $D_{KL}$ expression aren’t arbitrary (i.e. we aren’t working with $D_{KL}\left(P||Q\right)$), which restricts the amount this can tell us about $D_{KL}$ in general.

Yeah, I was vaguely hoping one could phrase $P$ and $Q$ so they’re in that form, but I don’t see it.
