It’s formatted strangely… an excerpt from the book at the bottom of the page? The authors don’t match. Or maybe that footnote’s for the images…
It doesn’t need to be any longer; one of the ironic byproducts of our newest computer companions is that, even in the age of short-form content, they produce reams of rubbish, very rarely containing anything of consequence.
This, in contrast, is refreshing.
[Edit] doh, the reference is explained in the first line of the thing.
