There is more than “unique web design” that cause reading issues with that article. For one the lowercase and as well as arcane keywords and organization. Not mention the autoplay music. I have communicated this to the author and they shrugged it off.

Reading mode doesn't work on Safari for me... I get a paragraph and sod all else.

So respectfully, do not make assumptions. And if you want someone to read the content, don't surround it with shite.
