I've read it. I didn't see any Anita parallels myself, but Whitfield often blogs about topics I think relate directly to LKH as an author. She's discussed "series fatigue" - as in, when an author should stop writing a series because they clearly don't have fresh ideas for it anymore. She's blogged about Mary Sues extensively, that sort of thing. It seems likely to me she's a former fan.

(Or should that be a negative reader?)
