Actually the advances in logic programming are quite compelling; answer set programming is pretty cool! I'm not sure why it's having such a small impact though - perhaps the shear number of low cost programmers available means that no one has to use it. Although I would have thought that high cost programmers equipped with tools like these could better justify their pay.
