I like this.
It rather drips with frustration but I have a great deal of sympathy with Matthew Stibbe’s 12 essential lessons for giving feedback to writers. We share some of the same customers, so perhaps it’s no surprise that I recognise many of the issues.
I would add just one other: Stick to your own deadlines. Almost without fail, clients miss their own deadlines for providing feedback.
Essential reading for customers of writing.
