Personally, I think we should start a peer-reviewed journal to review the reviewers.
Especially the really thickheaded ones, and the ones who ride their personal hobbyhorses into the ground.
(N.B.: Yes, I write book reviews too. No, I don't take them seriously. But I do find critical arrogation of privilege--both academic and in the lay press--more than faintly ridiculous. Trust me, sweetie, I do in fact know more about what my book is about than you do, no matter how desperately you would like to excise the author from the process entirely.)
