Good point.

I disagree. Microformats and RDFa have been integrated into a
significant number of pages. A couple of the larger CMS implement some
form of one or the other. Several government sites around the world
also implement metadata, such as RDFa or Microformat. Or both, they
aren't incompatible. Now, there's Facebook open graph protocol, being
discussed in another thread.

Interesting news, and timely, because it impacts on a couple of issues
related to this group: the polyglot document, as well as Issue 41.

The company integrated Google Rich Snippets using RDFa into the
company's web site, increasing their site traffic 30% as a result.
