HN isn't always the right demographic for feedback. I could this particular service improving to limit/filter feedback in a way that would make them more useful. Also, there are a number of other improvements that would really make this site a lot more valuable for getting feedback than HN, such as rating feedback givers, incorporating Silverback, etc.
