Given that you're involved with CSE, if you have ideas or results, why not investigate and publish them in a CSE venue, maybe a peer-reviewed conference paper, or whatever the scientific mechanism in your field is?

You say this is important to communicate, and it seems pretty central to your professional field, so I don't understand why you aren't using what I assumed were the mechanisms of that field.

As you said, HN overall probably doesn't understand your field, and, given that: do you think it would be good practice for HN to let its impression of a field be determined by a punchy domain name that bypasses the field's own review? (I assume your thoughts are much better than those of anti-vaxxers and climate change deniers who bypass the field.)

Separate from that, since you think someone has been rude, maybe approach them constructively about it? All of you are just people, who spend your days teaching students, and researching that.
