HTML5 Microdata: Welcome to the Machine | Nettuts+
I don’t think it is hyperbole to say that HTML5 will change the way that you think about web development. I welcome many of the changes as they make development easier, and the user experience richer. With any change, though, there is certain to be a bit of trepidation and controversy. One addition that certainly is not without its controversy is the Microdata specification, but I believe the benefits of this very simple specification are going to change how you look at your mark-up in the very near future.
