Good old HN. It's so easy to predict what will happen to a comment like this - in this case, +1 because it's mildly witty compared to the other comments, -1 because someone feels like it shouldn't be upvoted, and another -1 because it's at the bottom or is now relatively content-free compared to the newer posts. Will probably settle around 0 or -1, depending on how long the post stays on the front page. I'd gladly take the two-point hit in order to verify my suspicions.
I'll probably get more downvotes than you for this, and maybe even a "this belongs in Reddit" type comment, but you're obviously trying to pull "Winning by losing" on us. Besides, it's not a "prediction" if you say it after the event.
Ah, my prediction was wrong. But little do you know that I predicted that my prediction would be wrong because I knew that by openly anticipating my comment's downvoting, I would prompt you to upvote it. Dance, puppets, dance! How droll. Now excuse me while I go stroke my white Persian. Mmm... exquisite...
Don't worry. I bet there are lots of HN'ers who regularly experiment and A/B test HN comments & submissions, in order to learn what yields the best karma. A bit like SEO but just for HN.
