I tend to think of it as a serialising format with nice properties rather than a base data model. Tool support sucks for most languages right now and there is very few users who'd know what to do with a SPARQL endpoint , further there is no out of the box UI or UI toolkit in the open source space. DBopedia and other serious projects offer endpoints. And the nature of the format means one can federate queries across them . DBopedia is currently the defacto ontology/ starting point.
