Am I correct in thinking you'd parse any page with hCard that way, with
or without it having GRDDL mark-up?

Not sure what you mean, here.

What would be the advantage of that, for me or the site's users?

Again, not sure what you mean, here.

That seems a rather short-sighted view, if the intention is to allow
publishers to join the semantic web with the least effort.

Thanks for your help.
