hmm, interesting questions - tell you what - if someone will tell me 
what the answers are for the Web, then I can think about how we might 
make similar answers for the Semantic Web -- seriously, the goal is a 
cross-cutting technology, not a single solution engine.  That said, I 
do agree that some compelling success stories (esp in Life Science) 
would be good.  One thing I'd love to see would be some 
interoperability between the products of various publishers by 
linking their thesauri/vocabulary/ontologies.  We had a small demo of 
this playing with linking some Nature cancer work to some EPA cancer 
work via the NCI cancer ontology, but it was just a very small set as 
we had no funding to push this - might be an interesting thing to 
look at something larger scale than this as a use case...
