I get that you're being sarcastic, but... yes? It's fine to talk about topics where you're not an expert, but if you want to talk authoritatively about something, yes, I'd expect something at least approaching expert level.

Then, pray tell, what qualifies you to state your authoritative opinion on what we are permitted to talk about? We would like to see your credentials. /s

I mean, I'm posting on HN so clearly I'm an expert in... oh... damn.

You are right!

Maybe we should start an experts registry, so there is no confusion about who can speak.
