I've joked about doing this for a long time: the Internet, just without all those annoying people that disagree with you. So on HN, you would only see comments from people that had similar opinions, stories would be ranked based on those people's votes, and comments from people you (or your clique) have downvoted in the past would be hidden entirely. And this would apply to the entire Internet: comments, news articles, search results... everything.
I was only joking though, because a world where people are not exposed to differing opinions is a pretty horrible place. But this is what we're heading towards; a proliferation of cable news channels serving increasingly small niches, personalized search results, content filtered through twitter and facebook friends.

All that said, I'll probably still try it out!
