My original thesis topic (circa '98) intended to address these 
problems.  I don't recall anyone saying Semantic Web then, but logical 
reasoning/inference and semantic information retrieval from the Web was 
on a few people's minds.  (Sadly, a key committee member could not be 
convinced that this was worth pursuing, and I had to mothball it.)

Also, in addition to the ambiguous "people lie," I'd add 
"ontological/knowledge engineering is hard."  I think that malice and 
incompetence should be considered two separate problems that don't 
necessarily have exactly the same solution.
