Now inedeed the editors have written a long response on Kruger's blog. I will only cite their conclusion:
In sum, we appreciate Parker’s prompt engagement with ETNT so soon after its publication. While no book is beyond criticism, many of Parker’s specific criticisms stem from a misunderstanding of the scope of this project and its purpose. It is our hope that the clarifications we have offered here will help address some of these misunderstandings and allow for more productive dialogue on these important issues.
