There are two common social perspectives: information sharing vs emotional harmony. From one perspective, the other seems rude or insane. If your message is corrected or added to, this is a chance to be less wrong. But it is also a chance to be embarrassed and seen as less knowledgeable than you seemed.

Status seekers tend to assume the latter perspective, and therefor label such comments as rude, dismissive, conflict-seeking, etc. even if the OP had no such intention.

This is also 95% of what "help i'm being harassed online" comes down to.

Oh this explains so much. I've been raised in the optics that one should always share information in order to make the world better, didn't even think there were other reasons to, like, talk in public.

Since you’re not aware, a very common reason to talk in public is to gain something from one’s talking. The situation at hand looks a lot like that, and in particular gaining something at the expense of someone else in this case. If every ShowHN ended up directing everyone to an alternative project, no one would bother making Show HNs. Hence why it’s questionable about whether the top comment makes the world a better place, etc. That’s also why someone not apparently related to the library at hand could make the same comment without it being negatively received because they don’t appear to have anything to gain from it. I would instead encourage the poster to make their own Show HN the next day rather than hijacking an existing Show HN.

While I agree in general (there are better/faster approaches than virtual dom), it’s not very relevant to a Show HN about React-compatible performance improvements. Lit is not compatible with React, as far as I know. If there’s a claim that Lit’s approach can be compatible with React’s API, that would be a different matter.

To me this makes the comment come off as hijacking the thread to promote their own library, which really is quite rude. Not claiming this was spankalee’s intent, but you see this quite often on HN, people who keep mentioning their own product or library in barely tangentially related discussions.

It came off to me as "VDOMs as a whole are obsolete and a waste of time, including your project that you're excitedly showing us, so you should just give up on it". Which isn't just insensitive, it's not even really correct. There are much better ways this alternate approach could have been brought up for genuine discussion if that was their goal.
