How do we solve the filter bubble?

You need to distinguish between good and bad filter bubbles. Politics is a good example of a 'bad' filter bubble, but if I search for Python or Ruby, is it unfair to assume that I am talking about programming languages, and not rocks or snakes?

Yeah, that's an important distinction. Once text analaysis gets better, I think it will be important to mix the results.

We need a new place for objective, discerning conversation where facts matter. Print media and big three TV networks used to provide a fragile version of that for a while.

FactCheck.org and Politifact.com are steps in the right direction. I'd like to see a site that entertainingly covers news and issues, references other media but is willing to call bullsh*t on the media and politicians.

Decentralize information flows. (Good luck with that...) However, it's not simply a problem of getting served what you like. I can guarantee you Trump supporters were not getting served what they like.
