The comment also originally said "but even mentioning it on Hacker News will mean you get downvoted" before it was edited - personally I get very tired of pre-emptive complaints about downvoting.
Likewise. I may be in the minority but I won't normally downvote comments, only when I think it really is deserved, but complaining about downvotes -- especially in your original comment, before you've even received any -- well, I will downvote you for that.
