For my own business (epaper calendars), HN has been a great source of feedback from potential customers. People here are both direct and kind with their feedback.

The thing you have to keep in mind is that HN is a very specific niche of the Internet. But for a slightly nerdy, not mass-market, product like mine (or Kagi) this niche is a great place to grow.

You just have to be mindful to see the feedback through the lens of the fact that you're talking to a niche audience and keep an eye on what a broader market might be looking for if that's where you're planning to go
