Eli Pariser makes a great point about the dangers inherent in online "filter bubbles."

I have a thought. Perhaps there should be someone in our student’s lives whose job it is to make sure that students are aware of divergent points of view, and the danger inherent in not seeking alternative explanations of reality to what is easily handed to us. Students should know that they are forming these search bubbles around themselves, and be given options for circumventing them to find other perspectives.

I wonder who could do ensure this happens for our students? Any ideas on who should help students avoid living entirely inside these Internet filter bubbles?
