Most of the projects Shelley mentions use RDF in their core, and it's as true as it gets.
Re. cross-domain communication, many of the apps listed in [1] have some cross-domain element (virtually every RDF app uses DC for a start!).
RSS is something of a special case, but RSS 1.0 *is* true RDF, and as I point at [2], other RSS dialects can be transformed to RDF. Note also that the Raptor RDF parser now has a "tag soup" facility for handling other RSS dialects and producing true RDF.
NewsMonster [3] is one example (there are others) of an app that uses RSS and cross-domain RDF.
It's way too late too talk of RDF being DOA, it's adoption is accelerating. Check out Dave Beckett's resource list [4].
