Article comparing microformats to plain ordinary XML markup and concluding that microformats come out on the short end. "Microformats bring exactly nothing to the table. All they do is complexify the markup and make it far harder to address with XPath and other XML tools." Well, maybe. Browsers mostly read XML (there are some issues) but content creators don't mostly write XML. At least, so the proponents of microformats - who happen to be the people behind Technorati, which reads HTML, and not XML - would argue (Update: and in fact did argue). The concept of structured data is good. And I will confess, it is a mystery to me why we do not have easy-to-use authoring tools available.
