A fair percentage of my comments are downvoted, so it's not about opinion validation. I'm opinionated on a number of topics, and voice those opinions.

Sometimes I have a question to pose, or I disagree with the premise of the submission (sometimes I'm one of the few people to do so).

I'm a singular, non-influential person. I don't believe I'm exactly changing hearts and minds writing HN comments. I do like the discourse I get, though.
