I just finished reading a story I really enjoyed (in an anthology) written by an editor at a literary magazine I was thinking of submitting to. Is it okay to mention this in the cover letter for my submission? On one hand, I'm thinking it could help the cover letter stand out a little from all the boilerplate letters they receive. On the other, maybe these sorts of personal comments are regarded as brown-nosing or unprofessional, even if they are meant to be genuine.
