Well, the amount of valuable comments that would form a good discussion is highly correlated with the time a project being on front page, isn’t it.
But I think that requires eager participating from the submitter as well, not just drop your project and not replying to anyone, or not replying with an open mind/required perspective.
Good to know this and yes, ShowHN gathers more discussions with the author. One question: is it still true, that a submission can stay for days on /show for days? I read here recently that with the LLM trend of creating software /show became very overcrowded.

So yeah, definitively possible for it to stick around multiple days. Maybe not a full week anymore like it used to in the past, but still a long time. Conversations and engaged discussions can continue past that too, as authors check for replies then reply themselves, and so on.
