There is much truth to this post about about #math textbooks.
@oantolin Counterexample: John Kruschke's book "Doing Bayesian Data Analysis" it has cutesy puppies on the cover. Good book, used it a lot.
@drchaos @oantolin why puppies though?
@lizzard @oantolin I think he explains it in the book with "because they are cute and who doesn't like puppies?" I found it hard to argue with that....
