Bursting the Social Network Bubble

Bobby Friction has started to realise that his day-to-day online activities are not only being monitored but in some senses manipulated. How often he interacts with specific friends, pages or sites sculpts and filters everything and everyone he comes into contact with online. Since the Brexit vote and the US election these bubbles have become a really big issue - with talk of fake news, post-truth politics and online communities increasingly divided.
When, like Bobby, you decide you've had enough of living in a social media bubble, what can you do to change things? Is it possible for an ordinary person a user of social media to beat the system or is it only technology nerds who can do it? And really - is there any benefit to breaking out of the bubble?
