Which, of course, helps Amazon figure out what it doesn't sell, but should. I'd say it's a brilliant idea, but I can't help thinking, what took them so long?

It happens even if the comment I'm downvoting was posted a minute ago.

Thanks for pointing this out. I suspect there may be something genuinely broken with my downvoting, though, because despite having only upvoted for a good while, my downvotes continue to not count.

Alternatively, HN is keeping a backlog of my uncounted downvotes, and counting them in order as I make more upvotes. Thus, as long as there's a backlog, any new downvote I make will initially not count.

Personally, I think the >=0 net karma rule goes too far. I've tended to downvote more than I upvote because I drift towards policing behavior (not "grumpness": not all people who downvote more than they upvote can be classified as grumps, which is a highly subjective notion anyway), and generally have high standards for what I consider worthy of an upvote. Social moderation systems have to account for the variety of sociological roles. Not to mention, the net karma of the site may be negative, but a >=0 rule will never allow this state to be represented.

It is also impossible to determine what my net karma contribution is, and thus that the >=0 rule is even in effect. Net karma contribution should appear on a user's profile page, or at the top menu bar. I shouldn't be expected to track my karma contribution manually.

I have downvote arrows on comments, but at some point they ceased to affect the score. Which is to say, I click on the downvote, and the points go down by one, but upon reloading the page, the score is the same as before.

(And yes, it's happened enough times that I know it isn't just someone voting the comment back up in the intervening period.)

In particular, a false sense of moral certainty derived from an elitist denial of social complexity.
