After reading a few discussions over the last few days, I was thinking to my self that HN was better than ever, and very good (with one serious shortcoming). Even the echo chamber is much better than I remember.
EDIT: The shortcoming, IMHO, is the abandonment of politics. HN is the ideal place to solve that problem, with s sophisticated audience open to and interested in experimentation and in problem solving. The goal of propagandists is not to persuade you, but to paralyze you; to shut down real discussion and debate. HN is, unwittingly, capitulating and cooperating with them. HN is another success for them.
