I struggle with what to recommend when it comes to encouraging social media users to escape the filter bubble. Facebook especially uses your own history of shares and likes to send them more of what they prefer. This may be satisfying, but not a way to consider arguments or expand a personal perspective. I know I will not convince anyone to abandon Facebook, I cannot do this myself. What I will recommend is that individuals recognize this challenge and find ways to compensate.
What I propose is that social media users discover RSS. My recommendation, which I describe below, is much easier to master than earlier approaches to RSS. Find individuals you respect and follow what they write.
