This... was an unreadable experience. Gratuitous animations, football field sized paragraph widths, proportional/fluid CSS sizing (thought maximizing my browser on a 1080p screen would allow me to see more), bite sized paragraphs interspersed with information-thin graphic inserts, full width graphics that have a larger height than your browser viewport, text swooshing down the screen while you're scrolling because the above graphic is dynamically resizing.
I appreciate the desire to experiment with the medium, but it just does a disservice to the content.
I agree. It was pretty annoying. So are the new top/bottom footers on Medium. I sometimes open up the inspector and delete those two divs just to read the page, but most of the time I don't bother, give up on the article, and just close the tab.
Content should just be content. You shouldn't need Javascript to simply view a page. Even if this was all just CSS tricks, it's still pretty annoying. I mean it's a neat idea. Scrolling animation can be kinda neat if done right, but this totally wasn't. It takes away from the content, which is pretty interesting.
