It is worse than unnecessary. The statements made with them are too
often just plain wrong. They reflect poor understanding of knowledge
representation, of ontology, and of web architecture.

Sure, for some other kind of thing than Authors - for resources that
are information *about* authors. If you do this you should say so. (in
your RDF). By using foaf:primaryTopic in my rewrite of the recipe I
said this explicitly.

We don't and I predict we won't. This practice will be a dead end. At
least for purposes of the using the semantic web in a different way
than the document web. I don't think we need another shadow web that
is the same as what we have already. We need a supplement to the
document web that lets us do new, novel things, or that lets us do
things that are too hard to do with existing tech.

And I do not, of course. That thread shows a distinct lack of vision,
as well as a clear lack of experience in actually depending on
knowledge representation to do anything of importance.
