From Patrick Dunleavy:
I guess every researcher and academic writer has often faced the task of trying to upgrade a piece of work that just will not come out right. Sometimes it’s clear what the problem is, and colleagues, friends or supervisors who read the article or chapter can make concrete suggestions for change. But often it’s not so clear-cut. Readers are cordial but obviously unenthused. There’s nothing massively wrong, but the piece feels thin or unconvincing in some diffuse way.
