I've been on HN almost since its inception and anecdotally over half of the comments on posts like this are from cranks with nothing productive to offer beyond mean-spirited and tone-deaf criticism. There have been posts of projects by young teens that have elicited unusually harsh feedback. Very few people here are willing to charitably acknowledge the effort and vision of a fellow hacker and to provide supportive guidance. They are the epitome of the "akshually" meme.
