The reason I engaged in the thread is I didn't want OP to feel like their posting/their work was unappreciated. Putting myself in their shoes, I especially guessed that the "go to Reddit" comment would have felt dismissive.
I do agree that I (and most HNers) find explanations of inner workings interesting in Show HN (or anything on HN).
I also don't feel like people should be treated dismissively, but I think the GP in this subthread did qualify their initial impression enough, since OP did respond to them. It seemed to me like the person I responded to, a few replies deep, felt as though it was somehow overstepping to ask how something worked, and it was that take I was responding to, nothing backhanded toward OP, especially because they already established themselves to be as forthcoming as one might expect.
