I just searched your list of threads, through the first couple pages, and didn't see any such posts. While I did that, I did see a very interesting comment by btilly in a thread I hadn't visited previously, but I didn't see any comments by anyone with karma scores below -4. Does someone have a current link to anyone's recent comment with such a low score?

This one is now back down to -4 http://news.ycombinator.com/item?id=1021131

It's been -5 at least twice since posting it.
