This has nothing to do with the article posted or anything, I was just curious... who gets to pick the animal on the book cover? Do you (the author) get to pick, or does the publisher (O'Reilly) pick?
For whatever reason, I forgot that Go uses a gopher as its mascot. But like, their PHP books don't use an elephant.
I dunno, I was just curious if the author could pick an animal to be on the cover, or if it wasn't their choice.
