I don't know what to tell you because I didn't downvote any comments in this thread. You can see comments by other people here were downvoted too, including a direct response to me and HN prevents you from downvoting direct responses. All I did was post a comment from the blog you linked that was directly relevant to the criticism in the first comment to which I was replying. I mistakenly assumed that original comment and the linked site were both from the same person and I already apologized for that mistake.
My apologies, I thought your apology occuring in close proximity to an upvote was suggestive that it had been you changing your mind. Sorry for the misunderstanding!
