I doubt it, even though the Manchester syntax does make OWL much more 
understandable than OWL-in-Turtle.  Two reasons:

  - I think OWL itself is too hard for average developers (mid 33%). 
Although the various OWL constructs in isolation -- expressed in 
Manchester syntax, at least -- are understandable enough, average 
developers (the onese I've seen) don't exhibit the precise careful 
reasoning of a logician.  And they don't approach applications as a 
logician would, by starting with a few iron-clad axioms and rules that 
they've thought long and hard about, adding data, and then turning a big 
reasoner crank to get the desired results.  They approach applications 
more operationally, through a series of small steps that they can 
successively implement and test, to eventually produce the desired 
result at the end.

  - The majority of RDF (or graph database) applications that I see are 
much more like big data integration problems than semantic inference 
problems, and they typically do not need OWL.

There certainly are some projects that make important beneficial use of 
OWL -- based on the OBO Foundry ontologies, for example -- but from what 
I've seen, they're not generally done by *average* developers.  There's 
usually a PhD or two involved.

Anyway, that's what I've seen.  Others might have different views.
