I recognize that I am not alone in this experience and I offer no great solutions; my approach has been to review a manuscript for every manuscript that I author or co-author.
However, beginning with the article we published last year in Ecosphere, I have adopted one new habit. I am writing and mailing a thank you note to every handling editor that I work with, regardless of their decision. If I receive 22 manuscripts a year, I can only imagine the thankless job of an editor.
