We can thus safely assume a nonlame set of articles, and we also (so far at least) assume nonlame voters. And if you only have nonlame voters voting on nonlame articles, upvotes should be enough to pick the winners.
Honest question, and I do not mean this as a flame, because generally I quite enjoy Hacker News.
How, exactly, is the current top-rated story on HN, "How to Stop the Drug Wars" ( http://news.ycombinator.com/item?id=507509 ) related to.. news of hacking?
But I can't.
I agree with you, stories about drugs aren't what I come to HN for.
