Well, kind of but also not fully. Yes for the "global" frontpage, but for the /show list, your submission can stay on the "front" there for almost a full week, and with proper discussions already establish the first day or two, you still get valuable insights after days, even after it drops off.
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.
As of writing this comment, this is item #30 (last) on /show:

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.
