Which I hope all will agree is a worthy discussion point, who is right? Is XML over rated? Is the "Semantic Web" something even worth striving for?
Mattur said: "You don't need to use xhtml to achieve good SE results. And the semantic stuff doesn't really achieve anything unless everyone marks up their code consistently e.g. there is no w3c standard for how to markup breadcrumbs, global nav, local nav etc - presumably because these aren't semantic enough
And xhtml or xml gives ABSOLUTELY NO advantage to visually impaired users. None whatsoever. Most visually impaired people use IE with Jaws. Semantics doesn't come into it. It's really important that folks understand this cos otherwise people might start thinking that marking up in xhtml alone makes their content accessible. Accessibility is not a syntax issue.
I don't buy into the semantic web idea(l), as you've probably guessed"
Let the games begin.... ;)
BTW. If Mr. Berners-Lee would like to contribute to this thread, you'd be more than welcome ;)
