Are you suggesting, by extension, that if there are 300 submissions an hour (instead of per day) and 24 times more users that it will "all work out" and a set of similarly interesting things would pop out?
Quite possibly. When you submit something that's already been submitted, it counts as an upvote. So although things would fly off the New page too fast for most people to see most of them, interesting things would still get enough upvotes to get a toehold on the front page.
Actually I think the front page would be marginally more interesting at the consequence of many more stories going unnoticed. I'm also not convinced that it is possible for there to be 24 times more stories -- is there really that much relevant news out there? With 24 times more users I think we would see 5-6 times more submissions.
