I don't really understand why there is any debate about the utility of
metadata in general. Are you also against microformats? Title
elements? The meta element?

It seems obvious to me that a) metadata has been a huge success on the
web (the success of other techniques like NLP and PageRank
notwithstanding) and b) we haven't yet invented every metadata tag we
need. I think it is worthwhile to debate whether RDFa is the right
solution but do we really want to go back to a debate over whether
metadata is valuable or not?

This is useful stuff, right?
