> Thing is, HTML is a really fantastic and powerful way of describing documents. Meh. Postscript (and PDF, for that matter) do a better job describing the appearance of a document: you can place things exactly where you want them on the page. SGML does a better job describing the semantic meaning of the page (though arguably no one does it well): a <p> isn't really very descriptive. As you mention, HTML is lousy at UIs. HTML tries to do too many things, and ends up doing all of them poorly.
