I must just be missing something with my understanding of Google Now. I have a Verizon SGS3 running the stock/leaked/rooted jellybean. I sometimes see google now notifications in my notification bar and I have various cards appear when I manually go into the google search application. But, in reading about it it seems as if cards are supposed to "pop up" when applicable. Nothing ever pops up on me out of the blue like that. What am I missing here?
