FOUC and the Death of Progressive Enhancement
summary
Argues progressive enhancement’s moral claim fails and names concrete problems: FOUC and flash of unstyled content, spinners and flash of unbe havior dent from pipelined JS, webpagetest filmstrips showing two seconds of blank (Chase), and a past project (labs script loader) that deferred resources but caused UX issues. Proposes user-first fixes: a browser slider sending a request-fidelity header, servers choosing templates, Gmail’s basic HTML as real fallback, and cites Opera Mini’s nearly billion tailored Facebook users as proof these approaches work.
