How do you prevent the "filter bubble" from self-reinforcing the same perspectives?

I am pro-bubble, or at least, I embrace the bubble. I don't believe you can solve bubble problems by forcing people together. Me making decisions about how to do that would mean I have technical power over what other people read, which I oppose.

If you want a filter bubble, that is your (free) choice. Just because you have that ability doesn't mean you have to use it. If you can't force someone to listen to you, it just means you need to talk to them in such a way that they want to listen.

If I am free to filter you, and I'm still talking to you that means I'm really choosing that, which means our interaction has more meaning than if that wasn't a volentary choice.

If I filter too much, then my bubble gets boring! Also, since other people are involved, you are still fairly likely to meet opposing views via friends of friends.
