I just had a 40 minute bike shed moment thanks to this question.

How else would you indicate strong disagreement with a comment given the HN culture of well thought out replies and a zero cost binary device for weighing in on an issue, when you have nothing else to contribute other than "I disagree"/"I do not like your post"?

Upvote the commenter who makes the point you wanted to make. If no one else says it, you say it.

For instance, I upvoted Calcanis' comment (to rescue it from negative number territory) and upvoted the people who pointed out the insincerity / inconsistency. Both kinds of posts advanced the general knowledge.

I didn't have to upvote the more personal attacks on Calcanis. But it did feel pretty good. ;)
