It seems to me that having to polish all feedback to a publishable level of quality would (greatly?) reduce the amount of feedback someone could give. I've appreciated informal feedback that I've received in the past and if that was the bar that needed to met I would have likely never received anything back.

Agree. I was surprised by the length of some of the comments. Most of the editorial notes and critique I've seen are very terse.

I'd agree that, in general, you shouldn't necessarily aim for the same level of polish in feedback that you would in a piece for publication. Here, though, I think the excessive length of his comment undermines the credibility of his feedback and contributes to the sense that he's piling on the criticism.
