It's a mistake to think echo chambers are a phenomenon which only take place on the political extremes. Reddit itself is an echo chamber of tepid liberal orthodoxy and American exceptionalism, moderated by a former member of the Atlantic Council. A fish doesn't recognize the water it swims in.

Redditors might call a place like Hexbear an echo chamber for instance, but it wasn't the members of Hexbear who chose to isolate themselves. Reddit made that decision by banning them.

While this is true, I feel like there really is a difference between modern online communities and the ones that existed in the older era, before the so-called web 2.0 era. You can't escape bias at all, that should be any person's educated perspective, but there is a difference in degree that is sharper both on reddit and facebook groups and the like.

Ironically, twitter (which does skew left wing at least in some places), while having its host of issues, has a much lower degree of echo chamber-ness because there are no groups, everyone is thrown in a pot together. It does have the cancel mobs and all that but an echo chamber it is not, which at least proves "echo chamber" isn't the default final state of any social media platform.
