I think one of the interesting consequences of the echo chamber that social networks create is that everybody thinks they are in the majority. For example, if you view the comments on political pages, you'll often see conflicting claims that "the majority of people think X". I think each person making these claims genuinely feel that they are in the majority because their echo chamber distorts the proportion of supporting voices, and then you see comments like "who are all these people who voted for Y?" Edit to add: I think the problem is not only that people don't see views other than their own, but that they become unaware that other views even exist.
