"Echo chamber"? Maybe if we couldn't split into filter bubbles, we'd be forced to figure out how to talk to people unlike us over the long run.

I wouldn't describe HN as an echo chamber. It has elements, of course, but the quality of discourse here is really quite high and respectful. I actually read HN; I don't read YouTube comments, and I wouldn't even if that's all there was.
