Then I say that laziness, incompetence, and malice are three separate 
problems.

And I see that Cory Doctorow identified this with his unquoted third 
problem, "People are stupid."  He's talking about competence at 
expression, which, when generalized to Semantic Web, might include 
ability to distinguish concepts like "has-a" and "is-a."  I saw in the 
early '90s that pretty simple static object-modeling confounded eluded a 
surprising number of people, even after they received some instruction, 
and similar difficulty was found in the fields of Knowledge 
Representation and Knowledge Acquisition.  (If one has ever had the 
misfortune of reading YouTube comments, one might despair that we'll 
ever achieve even basic literacy by 20th century standards, nevermind 
what we think is required for 21st century expression on the Web.)

These problems, and others, are not insurmountable.  TeachScheme and the 
like will help.  Smarter approaches for the Semantic Web will also help.
