From my perspective, what you're saying sounds like nonsense. I'm not sure why you're more concerned with my karma than I am, but since you're curious: no, I did not spend much time thinking about the one singular downvote my comment received. It's pretty common for people to downvote for any number of reasons (downvoting for disagreement in particular is controversial but not against the HN guidelines), so I didn't really read into it at all. Sometimes a comment I make that receives a downvote will end up with upvotes a few days later, and sometimes it won't; sometimes a comment I make that initially receives some upvotes will end up neutral or worse. At the end of the day, I comment because I have something to say, and while others' opinions on that is potentially useful feedback, and a single upvote or downvote is literally the smallest possible signal that can exist about whether what I said has merit.
