It's a fable, so you can moralize about anything. But even so, why 
is Kerry using XML at all? All that overhead when n-triples would 
interchange just as well. And it seems Sam could do with an 
introduction to XPath :)

I guess people don't reap the benefits because they're in a hurry 
and don't always want tommorrow's complexities dealt with today's 
overhead. That's why RSS1.0 was resisted, it was too much to chew 
off at the time (RDF isn't entirely suitable for drip feed or 
evoutionary development). On the other hand, getting from XLink to 
RDF isn't so hard, so using XLinks or something like them in an 
RSS2.0++ could be a cleaner approach than forcing namespaces into 
RSS infrastructure.

[aside: It's interesting to watch RDF gradually align itself with 
the relational model. Maybe RDF will wind being some kind of RDB 
interlingua; if so I'd like to see some articles explaining how to 
make your relational model RDF friendly :)]
