This is primarily the reason why I stopped writing books and started making tutorial websites. There are so many interactive tools like <abbr> element that can make tutorials accessible to more people without inflating the content itself.
I'm still incredibly annoyed how constrained our web knowledge is to the feature set of ancient paper technology. We can click, hover, collapse areas, play videos and react to user actions yet most content is just these lazy walls of text. Event OP here uses footnotes that just scroll to the bottom of the page adding very expensive context switch for the reader rather than take advantage of the web browser capabilities like hover or modal pop ups.
Hello, I am just now trying to upgrade my blog. Can you please point me to sites that do this right?
An extreme example would be gwern.net -- specifically you might want to read https://gwern.net/about and https://gwern.net/design
Thank you. That is indeed quite extreme - I could use an article progress bar, footnote pop-ups (maybe, link back into article might be enough). Definitely not doing my own window manager. I'll try and read the rest of the design page with fresh eyes, maybe I'll learn something else.
