As someone who has launched countless of products, services, demos and more on HN (for almost two decades now) and other places, you can't really let those overly negative comments get to you. And it happens everywhere, not just on HN, even though people here tend to try to hit your soft spots, for some reason. But at least I've found that the overly negative comments on HN has at least a tiny bit of feedback one could learn from, compared to other platforms where it's just outright vile comments with zero feedback one could use. So yeah, HN can be ruthless, but so is the rest of the internet. At least here there is a tiny bit of feedback mixed in, and usually the rest of the comments have something insightful to say.
