Improving our Beta Feedback? (creative thinking welcome!)

It seems like the wide-open flexibility of an empty text field for providing the feedback may not be what we want on a long-term basis. I wonder if getting smarter about this might make sense?

Perhaps some type of "page-specific feedback"? Clicking on a "give feedback" could open some view that shows both the current page and some well crafted choices to help guide the feedback. Maybe we could make it easy to see what relevant feedback has already been received?

Are there ways to help users with aesthetic opinions to understand that such opinions are valued, but not high priorities, until we decide to look at that specific design again.

I'm surprised how few responses we've seen to the survey...

Any opinions on why so few? (just 3 at the time of this posting)
