It depends how you present the idea of adding machine-readable information to pages. After all, nobody is forced to do it, so you need to show some benefit before the "semantic web" will happen. Schema.org is doing it with the SEO angle: mark up your pages like this, and they'll be presented better in search engines. With VIE (https://github.com/bergie/VIE https://github.com/bergie/VIE) we take a different angle: mark up your pages with RDFa, and they'll become editable.
