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.
