One idea was to build a search engine that returns unpersonalized results. He talked about how Google will be moving into a "it's true, if it's true for you" kind of world. His idea was that it will open new opportunities. I think DuckDuckGo is one example, and they've grown and are doing pretty well. I think a lot of it comes as a reaction to Google, Facebook and other such things.
"It's true, if it's true for you" is also a great phrase worth remembering. It describes so much about the current world and where things are headed, and why some things seemed to have gone off rails.
