Hi OakLeaf,

Thanks for pointing out that we gave Knott credit. I looked into the link, which I thought was in the article, and it is - the words "The cutout test" are hyperlinked to the individual post Knott made. But the web page style simply changes the color of the linked text to red, which doesn't stand out enough to be an obvious link. So we're editing the article now to specifically give the link, and in a more obvious way. Thanks for mentioning that!

Respecfully,

Damon Rinard
