The Yahoo Search Blog has an interesting interview with Yahoo's VP of Emergent Search Technology, Andrei Broder. His basic premise is that search will switch from a pull model to a push model.
Search today is confined to putting in something and getting something back, a pull model. The next stage is for information to come in a context without actively searching, a push model. My favorite example is GPS. Instead of looking up your way on a paper map, you are in your car, and your GPS navigator gives you directions, shows gas stations near you, and so on. A year or two from now perhaps it will show you where those gas stations are, but only when you are low on gas.
Greg Linden notes that what Broder is really talking about is personalized information streams.
Is this really the future of search?
