Imagine search that didn't need to be found. Well, it's not exactly search, then, is it? More like mystical psychic predictions (unless you're the one coding), recommendations-based algorithms are along the lines of saying to searchers, "Don't call us, we'll call you." One of the problems with this sort of thing might best be displayed in the title of Irvine Welsh's short-story collection If You Liked School, You'll Love Work. It doesn't always pan out, does it?
