What would be interesting to me is to see the "what cards do I want to see?" logic used with the core set of Google Now information applied to these other app notifications. As in, Now learns what app's announcements or what kind of announcements from apps I always wipe from the dashboard, which ones I click through. Over time it tunes itself to reduce or stop certain kinds of notifications so that I'm just getting the notifications I'm going to want to see. Right now it's just the individual apps that control their notifications (the "give them everything" controls currently exposed don't really allow us to manage the deluge in the right ways). This could provide a better way to control all that.
