I partially disagree. Verbal communication requires people to do at least some degree of thinking if they want to respond to a view that they disagree with. Whereas social media allows people to "participate" in a discussion (in the sense that they produce feedback which influences the course of the discussion) using a mode of thought that can be summarized as "does this make me feel like pressing the upvote or the downvote button?" I believe that this latter mode of participant-community interaction is especially conducive to echo chambers, because it reduces any kind of content to a one-dimensional axis: does the community like this, or does the community dislike this?
