Notifications are the smallest bit of disposable, human-readable information that conveys something you care about. Their real-time nature gives notifications an immediate sense of importance. Well, my ass is vibrating, so it must be important.
If you want to rip on notifications, you can angrily wave your finger at the folks who believe discovering a thing has anything to do with understanding it. Notifications reinforce our addiction to the now. That vibrating ass of yours gives you the false impression that you know something, but all you really know is that something is different. The value of information does not decay as fast as the immediacy of the notification would have you believe.
