I'm somewhat confused by the section about the types of responses to writing, though. Did you include that to explain which types of responses you wanted to get from polls, or to describe which types of responses you wound up getting from polls, or for some other reason entirely? I think I kind of missed your point.

It was late when I wrote this, and it is early now, so forgive me for not making sense. I think by including that bit I was just trying to show that I was actively thinking about what I wanted to put into polls, and not totally half-assing the idea.

Re: specific types of nonevaluative feedback: The book does offer examples but it's all the way upstairs and I'm all the way downstairs, so I'm paraphrasing here and offering some of my own. While evaluative feedback can offer criticism and ways to improve, there are several kinds of nonevaluative feedback that can appear in comments, which might be remarks on:

the subject matter that doesn't necessarily discuss its treatment in the story (for example, In a fic about Character A: "Character A is my favorite!" or in a hurt/comfort fic "I love hurt/comfort fics")

the format or organizational structure of the fic ("I see that this fic is a drabble/multichapter/five times fic")

most often, "Thanks for sharing!" which doesn't necessarily imply like or dislike, or even acknowledge that someone has read the story, but it does express an appreciation for the author being able to share it. (Even "good job!" can be read the same way - maybe it doesn't always mean "good job writing this," but "good job posting and sharing it.")

It might also be useful to think of evaluative feedback as asking, objectively, how good is the story, while nonevaluative feedback simply shows that a story has been read and understood.

I think most comments I get on fics tend to be nonevaluative, but longer comments tend to incorporate aspects of both evaluative and nonevaluative feedback, like when readers pull out their favorite lines.
