IT professionals I've worked with do this kind of stuff all the time to keep employees from breaking stuff until it's shown that the employees can handle the added functionality.

I also disagree that HN's downvoting feature is an example of progressive learning. It's more about controlling trolls and setting expectations in the community. You have to earn your keep before you can negatively affect change. It's a feature of the meritocracy, not of the usability.
Not to detract from the discussion, but this isn't an actual feature on YC. AFAIK, nobody can down-vote (although editors can [dead]).
you can downvote comments once your karma goes over a certain score. but nobody can downvote submissions. no doubt that's what andreyf was talking about.
also, the karma numbers keep changing, which is why nobody seems to know for sure where the thresholds are. back when i got the right to downvote comments, you only needed about 20 points.
