HN has 300k daily uniques. If you filter down to 99th percentile, and again the half of the student population that has a shitty time through school, the article is going to be seen by something like 6000 people that fit the bill. Given that approximately 1% of the viewership will actually post comments, and you should expect to get sixty people who are willing to talk and have relevant experiences to share.

Note that this should be an underestimation - HN filters for the tech crowd, and by proxy, for IQ. Anyhow, my point is that you get less of the woodwork effect than my priors for how many relevant people would want to comment about it. My theory is that they've been traumatized into not talking about their experience as a gifted child, along with a side of imposter syndrome. And you're making that problem worse for that demographic. Congratulations.
