Web 3 or not, I'd see it as an extension of user sourcing, where users have various levels of moderation powers. I would guess these HN emails (I also received one recently and duly reposted) are triggered by some count of admins voting up unloved posts, maybe from a list filtered by a user karma threshold. As Jeff Atwood says about StackOverflow, it should be possible for a sufficiently privileged user to do just about anything staff can do. Not really a new concept as /. had the notion of metamoderation, but a richer model with multiple levels of user.
