Google is already showing different results per country and region creating bubbles of thought. News networks filter out information they think most people aren't interested in or (even worse) things they don't want people to know. Youtube messed up somewhere and after only a few clicks you're back in the "popular" video hell.

You're suggesting echo-chambers. I don't think that's a good idea. How are you supposed to see a different viewpoint if all you do is talk to like-minded folks?
