I think that as well as noting the means and medians of the questions about “how much karma” and “how many dollars”, it’s worth pointing out explicitly that in both cases the modal value was zero. I think the zeros reflect, at least for some of the people saying zero, positions that are somewhat different in kind from the non-zeros. (A rejection of the very idea that you decide whether a post is worth reading by looking at its score; the opinion that there’s no need at all for the book.)
That won’t always be true; someone who would pay $3 for the book will probably have answered zero. Still, the fraction of zeros seems like a relevant statistic here in both those cases.

Look at that, exactly the reason I picked 0.
