It's very abstract, even more abstract than a lot of everyday programming.  A lot of folks just don't do that well.  It's been remarked before in this thread (I think by you?) that there isn't a lot of good tutorial material out there on how to understand and use RDF-related tools and data design.
True.

Absent those things, for someone to blithely forge ahead linking data right and left is only going to cause trouble.
I think this may point out the problem.

I think of myself as someone to:
"to blithely forge ahead linking data right and left”
And I think it is obvious that I have a limited understanding of the semantics.
I think of it as the triumph of RDF and the enormous work that people have put in that I am able to do this.

Saying that we need to get people to understand the semantics better and make it easier for them is not the way to go - it is what people have been doing, and it isn’t working (for the purposes of David's thread).
We need to make it easier for people to “do” Semantic Web without understanding the semantics in anything other than an intuitive way.

Back in the days I have much enjoyed getting into Van Wijngaarden grammars and Denotational Semantics, but I didn’t actually use that knowledge much when programming in Algol68 or functional languages - and I’m sure most programmers avoided them like the plague.

We could probably put together a profile that disallows certain RDF usages and encourages certain idioms, and be done with that part of it.  Then the hard work would start.
