Overall, HN is pretty good because people here care a lot about facts. If, however, you don't think there are echo chambers here, you might want to look again.

Overall, HN is pretty good because people here care a lot about facts. If, however, you don't think there are echo chambers here, you might want to look again. The parameters are just different here. The echo chambers here tend to be related to > surprise, surprise < technical stuff, and things can get pretty heated and occasionally mean. Fortunately there is a lot of self-policing here, but on some topics you might notice excessive downvoting of non-inflammatory opinions that simply run counter to what the herd is thinking. People might not care about your gender/religion here, but they do focus on other attributes. I've seen people marginalized or dismissed as not being "real programmers" for using a glossy screen, PHP (not so much now, but PHP debates were really bad a few years ago), etc. On any given day, you'll find some people who think that Microsoft/Google/Facebook/Apple/etc. are crooked and evil and will never change their opinion. On the same note, you'll also find people who think Apple/Tesla/Elon Musk/etc. are infallible. More recently, if you look at the debates over the whether the new Macbook Pro is "pro enough", you'll see a lot of comments to the effect that "it's [not] like that for me, so it must [not] be true for you/everyone else [either]", which is pretty similar to the bubbles people sit in the non-HN world too.
