We're all definitely in an echo chamber. Hacker News is an echo chamber. So is Reddit, FB, Twitter, etc.
This is what happens when, as an industry, we move towards "personalization". All of our "personalized" feeds allow businesses to increase their ad revenue, but it siphons us away from the rest of the world. 30 years ago, we were beholden to the large media outlets, which is also bad, but I believe we've overcorrected. All of our apps are just too personalized and they don't work hard enough to tell us what we should know, as opposed to what we want to know.
