Anything this common becomes noise, since it doesn't add any new information.

Heres' another way to look at it: since the idea of HN is to be intellectually interesting (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...), repetition is the most important thing to avoid (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...).

I'd say the Who's hiring post is by definition bound to not have intellectually stimulating discussion, so this logic doesn't track for me.

That's a good point! But I'd still say (1) we don't want it to be a thing anywhere on HN, and also (2) these threads are already overwhelmingly large.

I understand where you're coming from.. My takeaway is that a HN post is not the right tool for the job in this case. (pun not intended)
