If you expect a comment of yours to be downvoted, perhaps you should consider whether or not the comment in question is actually contributing to the discussion. I imagine that your original comment was downvoted because it expressed your feeling that this was not worthy of submission without including any reasons supporting your opinion. You seem to be surprised, in general, when people disagree with you. Try convincing them, or considering things from their points of view.

-4 is the current system-imposed limit. When a comment reaches -4, it's a reasonable inference that there may be many more than five participants willing to downvote it.

I wonder what would happen if a similar system was set up for upvotes? I guess that would make it harder to tell the relative worth of valuable comments. Nevermind.... scrap that idea.

-4 is the limit.
