I was very blunt and impersonal. People worked hard on a thing and my first reaction was criticism, without even the added overall view of "I love this thing, but here is a small thing that bothers me." I could have been more courteous and human about things.
I stand by the points I made, but I could have been friendlier. I normally make an effort to be friendly as I can about things, but I absolutely did not here. I hope that nothing I said came across as vitriol, but rather, valid criticism. I'm a strong believer in criticizing the things you love, but I need to remember that random comments on HN aren't the place where people know I love the thing, and my criticism needs context.
So no, it wasn't really that odious, but it was other things. Do I feel stricken with guilt or remorse about what I said? No. Could I have been friendlier? yes. Should I have been friendlier? Probably.
