A very enjoyable read about typecasting and typesetting:

I have great interest in typesetting, and have gotten great joy out of TeX. Unfortunately, most of today's text is belched onto users' screens using HTML, which will hopefully one day be able to produce a somewhat respectable rendering.

(Though, most everything I do is plain text on a VTE.)
