Filter bubble might be addressable using ideas related to "information quotient": If FB decides it's worth trying to "show you the content that will most effectively challenge your views", then we pop the filter bubble, promote good content, etc etc.

Note - I don't just mean, "content that disagrees with you", because 95% of that is shit (Sturgeon's Law), but, content that effectively disagrees with you. That actually has a chance of changing your mind.

Information Quotient, as I understand it, is the idea of "What information will teach me the most?"
