“If you believe in human-readability of your markup and in the power of XML, and your website isn’t valid XHTML, you’re contradicting yourself.”
Refined RSS feeds (kottke.org)
I’d damn well better shut up then. Although I do have a super lovely Typepad (machine) created XHTML blog in the works.
I still think that RSS can be both human readable and match its potential, its not to do with namespaces or the RDF model, but the fact that the RDF syntax shoehorns into XML in a way that there are double statements that read like legalese.
