Very good point, and just to repeat it and clarify it: Many people coming into the Semantic Web field believe they "need" OWL DL and Tableau reasoners to do useful stuff. However, there is a significant "price tag" attached to those technologies. Especially on large models and databases, many OWL DL inference engines do not scale well. Furthermore, the expressivity of OWL DL is often not sufficient to express knowledge in a way that allows users to get interesting results back. Writing smart SPARQL queries (with a bit of on-the-fly- inferencing such as rdfs:subClassOf*) is often a much more expressive *and* faster alternative. With this in mind, I encourage you (and everyone else who starts semantic web projects) to review whether you really "need" OWL DL inferencing to express what you want and to drive your application.
