From a note in the latest issue of Nature:
Comments from referees reviewing a paper can sometimes be less than
polite, making it tempting for authors to send equally rude replies.
But a trio of recent blog posts emphasizes the importance of
professional, constructive responses from authors. The posts, by
three ecologists, aim to help researchers to avoid common pitfalls
that can sink their manuscript's prospects. Commenters on Twitter
appreciated the guidance.
