I got to say I have given up worrying about why people are downvoting what I say, I do have a suspicion that I have a couple people who when they see my name automatically downvote - oh it's that guy again - although I don't think they search me out to downvote either.

on edit: at any rate I upvoted it as you're right, seems an encouraging nice message.

FWIW across ~10 years of HNing my sense is it's pretty hard to land on > 1 person's shitlist, and while it's unlikely you've garnered a coterie of haters, it is the iron law of HN that complaining about--or speculating about potential--downvotes attracts many downvotes.
