It's an interesting idea for sure, but I'm not sure how or if such a thing can exist. Moderation becomes a headache, and well, a lot of truly brilliant people I've met in life have zero interest in debating it. How do you keep out the YT commenters, Fox News or r/politics commenters, etc?
It would be interesting if HN had some bucket like /offtopic, for things that are flamebaity and removed from the main view, but I fear it would attract the aforementioned people who only ever troll there, and dang probably having zero interest in mod'ing it.
formalized highschool and college debate is pretty much this
It was really boring for me, and at times a lot of work. However, one thing I appreciated about it is that at times you'd obviously be arguing a side you don't necessarily agree with, and learn a ton in the process. Also surprise yourself a bit in how convincing you can be. In a way, I wish everyone had the time and effort to research a POV they don't agree with, but as if they did.
Probably great training for a lawyer or paralegal, perhaps even public speaker, but I personally didn't find a lot of joy in it.
What do you mean by this? I did a few different forms of debate in highschool and this seems like a really surface level characterization of just a few of these sub-types.
