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.

If you have downvoted a single user many times in a row, you might have triggered an anti-karma-bombing feature. http://www.google.com/search?q=site%3Aycombinator.com+karma+... I would email pg at this site to inquire, and be ready to apologize if an apology seemed called for. Good luck.
