Obviously it depends on what you want to happen to your data.

If you're publishing from one of your servers to another, or using
some closed system, then obviously there is no reason to do more work
than necessary.

But if you are trying to publish metadata that will be consumed by
other services, then RDFa is an option that is attracting wider
interest. I'm working on a project to allow UK public sector jobs to
be published for wider consumption, and I can tell you, I'm not
looking at RDF/XML!

I'm looking primarily at RDFa in web-pages, a little Microformats for
compatibility with Google's social network processing and client-side
tools like Operator, and then Atom feeds with embedded RDFa for
consumption by services like SearchMonkey.

I can't comment on that example, but ultimately there is no need for a
URL for an HTML+RDFa page to be any different to a normal one.

(Although I might have missed your point, here....)
