For anyone else curious, you have to go into your HN settings and change showdead to YES in order to see all the majority of his Comments. Only two show up if not.
Ah well, not great. I didn't know his HN accounts, I think I mostly read his site for TempleOS and something else (can't remember, it was long time ago so this was mostly a gut feeling).
It's true it feels like it comes from a different place, but yep, not great.
