Now, if you look at OWL, as powerful and fundamentally useful as it actually is, what's happened to it over the last 12+ years? Nothing but confusion due to syntax level issues, all at the expense of its underlying syntax agnostic model.

OWL is not a failure, if you Google up you'll notice I've published a 
plethora of OWL utility demos. My point is this OWL has had a bad wrap 
due to folks not separating Syntax from Model.

Back to LOD, DBpedia, and friends. If you notice, OWL hasn't been 
naturally pulled along with the Linked Data uptake wave. That's because 
RDF/XML obscured the pathway to comprehending its purpose. Manchester 
syntax hasn't gained traction. Turtle enables easy demonstration of OWL 
utility that understandable to a variety of audience profiles.

Imagine if SPARQL wasn't based on Turtle, or the spec inferred the query 
patterns could be in any RDF syntax since Turtle is but one of many etc..
