For good or for bad, its part of HN culture when someone shares a personal project. Most people I think know to take it all with a grain of salt, there's often good feedback amongst the unconstructive or plain wrong - see https://news.ycombinator.com/item?id=9224 for a classic example.
I have the perception that HN is quite ruthless with the feedback. I appreciate constructive criticism, and HN is mostly constructive and self moderates against non-constructive criticisms, but for me, HN is the platform that gives me the highest anxiety when I think about launching something - more than product hunt.
Edit: and I’d be remiss if I didn’t mention that if you only give someone encouraging words and positive feedback , you are doing them a disservice by stunting their growth or sending them down a wrong path.
