Noticing this aggressive downvoting trend quite alot on HN lately. Perfectly valid inoffensive arguments are downvoted just because the downvoter disagrees with them.
I reserve downvotes for rudeness and demonstrably wrong/misleading comments.
Personally, I use upvotes to reward new knowledge or an interesting argument in a comment, I don't upvote every comment I agree with, and downvote only if the comment is offensive.
With all due respect, I don't find it particularly relevant what one guy said 6 years ago. I don't care whether he created HN or not. He's no longer an active participant.
I'm not!
