Really love this list of dos and don’ts when editing someone’s work. It’s put out by author, blogger, and former literary agent Nathan Bransford. Point number eight, Don’t Overdo It, especially speaks to me because we’ve all been asked to critique something that needed a lot more work than comma correction. If a whole section needs a rewrite, line editing is hardly worth the effort.
Check it out for yourself and let me know if you agree with the commandments or might add/delete a few. Happy writing!
