I think there's some significant points in the linked article. Specifically, the problem of separation of format from presentation has been the largest conflict with the 'Web.' Right now, we're heading towards treating HTML like we do other document formats: a type setting format. But it's still arbitrary as to how each browser (even on different platforms) will display a document. I'm not sure I share the author's sentiment in blaming Tim Berniers Lee, but I think it's true that folks like Netscape and Microsoft cemented the hacks that Tim created at the time which in itself set the standard which we all use today.
Also, the sooner we abandon the HTML standard for transmitting documents, conveying state (via applications), and to consume content the better we'll all be off (my opinion only) since it will allow developers to create standards that fit the requirements of each without having to accommodate the other(s).http://www.theregister.co.uk/2014/03/12/world_wide_web_at_25_for_luvvies_and_vcs_or_everyone_berners_lee/
