I think Patrick Mulcahey's commentary about Nixon's feedback on his LOV scripts was that she was a severe micro-manager and her feedback ultimately wasn't helpful to him.
Found it, it's from a Santa Barbara fan site:

How did you start in Santa Barbara ?
Thereby hangs a tale. After working with Douglas Marland on Guiding Light and then on Loving, which I hated (and where Agnes Nixon was like some psychotic schoolmarm on speed, making copious condescending red-pen "corrections" in the margins of scripts - "You used the same word on page 2 and on page 34 ! Too repetitive !") - after that, I decided I was done with writing for soaps. Douglas was the best. He'd taught me more about writing than any ten literature professors ever could have, plus I'd won an Emmy. I figured I'd never have another experience like that, so I decided go back to what I knew best : waiting on tables and writing plays at night and being a starving artist again.
