I interned at a language engineering research lab in 2003-2005 and I heard the exact same sentiment about DSL's from most people working there. All the typical examples are techie languages (SQL, Rake, ...). I've almost never seen a non-techie DSL whereas that is ultimately the promise of the concept. It's sad the DSL story has barely changed in seven years. I haven't read the DSL book, but if it's about parser/evaluator technicalities as you claim, one might as well (re)read SICP.
