Don't get me wrong, I love HN. I never thought I would have to write something like this.

However, HN is indeed a bubble. Any criticism of the community (like this one) will get voted to the bottom and never be seen. However, a quick look outside HN (e.g. on Twitter) will reveal that HN threads can often be nothing short of ruthless. Maybe it's just me, but I've seen a rising number of these recently (this one included).
