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.

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.

Most ironic of all, data quality and integration dexterity are continuously seen as shortcoming of the aforementioned, the very thing OWL does very well. Why isn't that the norm today?

OWL isn't a failure. My point is about OWL uptake and appreciation.

That's because you find RDF/XML convenient. Unfortunately, you don't 
reflect the majority.

Syntax multiplicity isn't the defining issue re. OWL. A specific syntax 
is, and that's RDF/XML. And if you are interested in history you'll 
notice RDF/XML has had the same effect on other aspects of the Semantic 
Web Project. Basically, every time its moved away from the "front door" 
appreciation, comprehension, and momentum follows.

Same applies to you. We are both entitled to our subjective opinions :-)
