1. Are those topics being censored? You don't seem to know that is true, you're just making assumptions about what reach should be. They open sourced the ranking algorithm and just refreshed it - can you find any code that'd suppress these topics?

2. The media also amplifies people's interests which is why it focuses on bad news and celebrity gossip. How is this unique to social media? Why is it even bad? I wouldn't want to consume any form of media that deliberately showed me boring and irrelevant things.
