The important subtext of this thread is that, when we're talking about functional typesetting, the solutions space is pretty constrained. There aren't that many things you can do with a text face (vs. a display face). And you already have available to you extremely high-quality, well-hinted text faces at a full range of weights.
(I do not think it is the case that HN shuns design and I do not think you will be able to support with evience a claim that I'm ignorant of type design or commenting in bad faith).
I'm not blowing you off. I'm taking your argument seriously. It just doesn't hold.
This is well put and thanks for engaging with the argument in good spirits.
I imagine that fonts often matter a lot for brand identity and specific use cases (like programming) will also have specific aspects of importance (like ligatures in particular to a lot of folks and being able to tell symbols apart at a glance so IloO0 etc. don’t present issues, but for many use cases some utilitarian “good enough” choice will suffice, because there are a lot of competently made free fonts out there.
