I'd rather look at this club as some sort of 'code golf' than take it seriously as a manifesto. Actually, even as a manifesto their point is valid, as a form of minimalist art. I consider the web as to be a canvas for many artists too. You don't need to agree to admire their work (e.g. dadaism is not frowned upon today)
Ok if this is the serious intent (minimalism) then they probably want SGML, not HTML. They would also not want this delivered using the seven layer burrito that is the OSI model.
