Without agreeing or disagreeing with the unnamed official, I have to admit that HTML5 feels a little like HTML3 to me -- it's following up a lean markup language (HTML2, HTML 4/XHTML 1.0) which was explicitly defined as an application of a well-defined general purpose language (SGML, XML), with a new version which is not so defined, and which contains a bunch of features which everyone wants right now, but which feel a little shoe-horned into the new standard (anyone remember HTML 3 Math mode?).<p>I suspect HTML 6 will be a lot more interesting, being the same sort of orthogonalization of the parts of HTML5 which actually got implemented by browsers that HTML 4 was for the mess that was HTML 3...
