My plea to designers and software engineers: Ignore the fads and go back to the typographic principles of print
How the Web Became Unreadable
Kevin Marks

This, so much! And not only for creating readable type, but for all aspects of design such as inserting pictures and text quotes. Even on my great PC screen, distractions to my eye hurt readability and waste time. Animated images are so obviously rude I wonder if people aren’t looking over their own work. Book designers know how to prioritize readability, and other designers need to study their work. Especially picture books.
