I am not a ycombinator staff member (I even have no own business or live in USA or speak English native) but this site is a friednly free-to-use service, not Paypal or Starbucks where you can blame the staff for delivering the coffee too hot.
There's too much of a "oh well, it's free so what do you expect" attitude. It's because of this attitude I have had so much difficulty in getting some open source products adopted in some places I've worked at.
I would understand if this was a one man band operating out of his bedroom in his spare time but HN is slightly bigger than that.
Besides, support replied, they just had to follow up a little more and be a bit customer service focused (granted we don't necessarily have all the details)
The OP demonstrating quite a bit of hubris assuming HN is broken just because they aren't getting their email - there's quite likely a very easy way for HN (is pg doing all this himself?) to see many many password reset emails going out every day and successful logins from those accounts shortly after. If _I_ were seeing that at my end, and still having someone insist my end's "broken", I'd hover between assuming they're either not competent enough to be worth spending (free service) customer service time on, or they're trying to social engineer access to someone elses's account. And I'd politely brush them off - just as HN did…
