I think it's really difficult to tell if they are dying or not. I don't think MAU or DAU gives the full picture as it doesn't tell us what people are using it for, what sort of new accounts are coming online (are they real people, bots, businesses or what?), and how active people actually are. Are people logging in for easy auth or are they spending more or less time actively browsing the site. You're right that HN is not the right place to judge this. I will say, as someone who works with high school kids, almost none of them have seemed to use it over the last 4-5 years.
