I consider RSS 1.0 a horrible format for two reasons. It's a poor RDF  
format because of the weird syntax requirements (you have to do a  
specific XML serialization or it's not valid) and because it doesn't  
SPARQL well (rdf:Seq). It's a poor syndication format, because RSS 2.0  
does the same job in a simpler way, and Atom does the same job in a  
*much* better way. So RSS 1.0 is the worst of both worlds.

On the other hand, as Leigh pointed out in a different thread, Talis  
uses RSS 1.0 plus some RDF properties borrowed from OpenSearch to  
express feeds/lists of search results on the Talis platform, so  
there's some precedent for using it in the way you said, and this also  
makes RSS 1.0 not quite as dead as I thought/hoped.

Content syndication a la Atom/RSS is not a problem that requires RDF,  
IMO. I would probably use Atom with RDF payloads. I love RDF as a data  
model, but notifications about updates to items in the data model do  
not necessarily have to be encoded in the same data model. (Although I  
am prepared to believe you if you told me that you really really need  
an RDF-based format, so no need to argue that point.)
