The document discusses the history of HTML and CSS standards development over time. It notes that in the early years of the web there was a lot of innovation, but after the author "went pro" there was only one major HTML release for a long time. This was due to the W3C prioritizing semantics and multi-device support over new features. The WHATWG group formed because they did not think the W3C was well-suited to further HTML development. The document expresses frustration with the slow pace of CSS standards development at the W3C. It advocates for more designer involvement and recommends experimenting with new features, building use cases, and opening dialogue to influence standards development.
