The problem is performance: since piggybank is not doing the HTML
parsing and the HTML parser is not aware of RDF/XML in comments, we need
to pretty much explore the DOM for *every* page you click.

We'll need to do it for creative commons anyway.

But it really doesn't hurt if you put a <link> to the RDF data as well
(and Google can just ignore while we and other crawlers might prefer
that rather than just scraping the whole page looking for RDF/XML
embedded in comments)
