Ask HN: How to give submission a second chance?

It's really a pain sometimes to watch brilliant and thoughtful submission sinking unnoticed in all the noise. Should I just accept the way it is and move on? Does anyone has examples of great submissions we've missed?

I don't bother submitting stuff any more because:

1) There's too much noise on the new page.

2) It matters which at what time of day you submit an article.

3) There's too much chance about whether it'll been seen or not.

4) Someone else will post it with a slightly different URL (see above), and that's the one which will be noticed.

I am, of course, very grateful for everyone else who posts stuff. There's usually a good article or two on the front page.

I suppose the question we should ask is if it matters if decent articles are missed? There's lots of text out there on the internet.

[edit: Removed three trivial ways to defeat the dup detector.]

I don't think so, but that's not really the point - a brilliant submission that sinks without ever being seen won't have a lot of discussion either.

Better yet, make it cost you 10 karma to submit it in the first place and then the noise on the new page would all be gone.

And better even yet, allow you to spend more karma points to give it a higher initial score.

And still better, when a thread gets archived (when the comment thread becomes read-only; happens after some N days), add its current score delta (the number of points it has now, minus the number it had when you initially invested yours) back into the user's karma, times some coefficient (possibly just 1.)

And finally, allow anyone to do this (invest karma; reap eventual score-delta rewards), not just the initial poster.
