I tried to view the page on iOS and it was definitely unfamiliar.
Even on desktop I imagine it would feel more like a presenter view in PowerPoint than a blog post. Unless it somehow looks radically different to on desktop than what this mobile view looks like.
I usually have all windows maximized so normally this is not a problem for me but I've noticed other people, (especially mac people), don't like to maximize their windows. Here is one screenshot to show an example on Windows where I have a 4k display with two browser windows side by side each window at 50% so texton the image is unreadable.
Thanks for the suggestion!
