What I don't like is low-effort memespeak on HN (even if I agree with the sentiment). This is one of the last places that has kept that at bay - until recently.
I'm aware of that guideline which is why I didn't say that exactly.
Regardless, I don't think silent downvotes really cut it anymore either - nowadays I tend to run out of them after reading only a couple submissions with active comment threads.
I think one-offs like this are ok, and I'd like to think mine was a step above "low-effort" ;) Besides, check out the discussion it spawned!
It's those long chains that end up being an out-of-order recital of some famous TV/movie scene that really irk me, personally. Those and similar are cases where the value is only in recognizing the source and getting that dopamine hit, and not in any further contribution to the discussion.
