Really cool idea, and I really like that it keeps about the same chars per line, but the breaking of native browser resize leaves me questioning how good of an idea this actually is.
Text sizes are a hot mess — but interesting concept.
Great idea, but the text is way too huge for me to read at all on desktop without resizing it down to mobile-width. If the desktop legibility was worked on this would be excellent.
It also took a good few seconds to load the responsive stylesheet.
