Since, according to k00b, Stacker News is still in beta, it doesn't much matter how effective a 10k downzap is. We're trying to work out the mechanics of the site and establish proof of concept.
If Stacker News becomes larger, suppressing good content will become more costly. If this still seems like a problem, maybe we'd experiment with zaprank models that also account for how many zappers there are on each side and how trusted they are by the community. We could also experiment with personalized feeds some more.
Ultimately, downzapping does useful stuff and is an obvious part of using money as the moderator.
