Unrelated to the primary content and purpose of this post but this was actually a pretty interesting use of an image map. Sadly the polygons don't seem to align that greatly with the image, nor does it seem like mobile Chrome applies the tap-helping algorithm it uses to help you tap the link you "intended" to tap (rather than were your finger actually registered its coordinates).

I was also surprised to find that there's lots and lots of text stowed away in the HTML comments. Perhaps it's a peak into how this particular article evolved?
