I was shocked to learn the terrible news that Derek Weiler, editor at Quill and Quire, has passed away at the ridiculously young age of 40. Derek and I had many heated arguments here in the comments and through email. (He once called me “pathological.”) But despite our feisty exchanges, Derek was a very fair-minded and reasonable man who deserved to live much longer. And I enjoyed our volleys. He had the balls to take me on, and the decency to understand positions that were contrary to his own, which I can’t say about a lot of editors. My profound condolences to Derek’s family and friends for this terrible loss.
