Hacker News isn't a great place to discuss papers generally. Having a productive discussion around a paper requires at least reading and understanding the abstract, and the most successful content on HN (sadly) is content where people can jump in with an opinion purely from reading the headline. Anyone know of any forums that are good for discussing papers?
But the gold standard is a small signal or discord community of like-minded, fairly tight knit friends. You may have to organize this yourself
