I think it is exactly how people are behaving. And I can even recall witnessing many people first hand who flip a newspaper to the sports section. Never learning anything about science news, medical news, unless it’s some kind of social column about a diet.
People wanting to cut out and block things they don’t want to read in a newspaper is what I consider the “default behavior” of most of humanity. No surprise they do not care about the news their friends share. An intelligent computer system that filters out (based on topic/content study) what they don’t want to see before-hand is always going to be popular with such people.
