I disagree. Though maybe there isn't all that much here (certainly nothing new/groundbreaking), I still think it's useful advice coming from somebody who knows what they're talking about. Maybe it doesn't deserve the all the upvotes/attention it receives, but that just goes to show you how important credibility is.
It was actionable for me. I just rethought how I was collecting feedback, which I was doing right before I saw the post.
Actually I found a lot of value in the HN comments to this post. Thanks to 37signals for inspiration!
