One of the things I've found interesting about discussions with the
RDF/Semantic Web crowd is that many of them fail to see that moving to
ontologies and the like basically is swapping one mapping mechanism
(e.g. transformations using XSLT or regular code in your favorite OOP
language) for another (e.g. creating ontolgies using technologies like
OWL or DAML+OIL). At the end of the day one still has to transform
format X to format Y to make sense of it whether this mapping is done
with XSLT or with OWL is to me incidental. However the Semantic Web
related mapping technologies don't allow for the kind of complex and
messy mappings that occur in the real world. 

Anyone who doesn't think there is two sides to an argument is probably
involved in one.
