Yes, but limited. It'd depend on whether the mods reupped the post the next morning so it could have a chance of hitting the front page or if a dupe managed to get through (which does happen). Either because the system permits it, or because the submitter added a #nonce to the end.

If the mods reupped it, then it'd work out really well for the original submitter. If karma mattered, I suppose it'd be worth trying a few times to see how it worked out.

Yeah, I'm not going to bother with it just for imaginary internet points, but I bet if you wanted to take it further you could analyse the top sites that hit the front page and poll all of them.
