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!

Thanks. It is rare to have an anonymous internet interaction in which we can both admit where we were wrong.
