I think the theory of domain-specific languages is very valuable, even if there's rarely a need for a full implementation of one. As I see it, a DSL is just the end-state of a programmer creating abstractions and reusable components to ultimately solve the real problem. The nouns and verbs granted by a programming interface constrain how one thinks, so a flexible and intuitive vocabulary and grammar can make the "real program" powerful and easy to maintain. Conversely, a rigid and irregular interface makes the "real program" a brittle maintenance nightmare.
