Looking at the abstract, I’d actually subscribe to most of the statements. I think you guys are preaching to the converted most of the time, which is not the best way of spreading the word, assuming there is at least some truth in your gospel. Take a look at the EMF or OAW websites: lots of namedropping and no clear messages. If they cannot state clearly on the very homepage 1) what problem they’re trying to solve and 2) what benefits their solution has, then why should anybody bother to read on? And the tutorials there are either too simplistic or too advanced for beginners.

Oh, and you forgot another reason: It’s old wine in new bottles.

People have been writing their own languages using yacc or Antlr and generating code from them for decades – and now you call it a DSL: cool, so I’ve been using DSLs all these years without knowing Ever heard of SDL? (No, that’s not just a typo or a permutation.) Graphical modelling and code generation ever since the 1980s…. (And a ghastly toolset with vendor lock-in and insufficient integration.)

… and why does it work?
