"But without a compelling app, or even better, a killer app, to pull it through, it doesn't matter what the format is….Anyway, I don't see any killer apps in the RDF crowd." – Dave Winer
My position lies somewhere between Tim and Dave's positions. Trying to build a killer app with RDF is somewhat like sculpting with Jello, difficult. Still, I have been surprised many times in the past by what people can do with very little.
One lucky guy or gal out of millions of non-RDF gurus out there might have the right stuff to pull it off. Trouble is, the RDF syntax is preventing RDF killerapps from being conceived like some intellectual diaphragm.
