I agree with you that the jump from the quoted comments to my passionate statement ("If you don't like my work...") was extremely abrupt. It seems to indicate that I believed the criticisms to be ad hominems directed at me.
Refuting the ad hominem ad-hoc, without an example was childish behavior on my part and I would like to apologise for that bit unreservedly. I also realise that it is VERY ironic considering the nature and topic of my post but I hope the rest of the post still makes good points.
Nope, I am not ashamed about the 'appeal to emotion' because it wasn't an appeal to emotion. It is something I personally believe and I'd like to stand by it, please. I think that anyone who's created something deserves a bit of admiration/praise along with the criticism and in that regard the example fits perfectly, IMHO. Let us agree to disagree here?
I beg to differ about the 'honesty of the criticism' and the 'concreteness' of the three issues you mention - IMHO, they were disguised as insults. The same points have also been brought up by others in the same thread in ways that are far better at promoting a conversation and a learning experience, in general.
It'll please you to know that the original creator of the Show HN (TuringMachine) was a far better man than I and I was thoroughly impressed by his responses. I, OTOH, was quick to express my anguish in a public forum and I have received some very interesting criticism myself. Yours is definitely one of them, thank you.
