title: Abusing NSNotificationCenter
body: <p>NSNotificationCenter is really cool and we can build very extensible apps with it. My question is: Can we abuse using NSNotificationCenter in an application i.e. use it intensively or is it not really a good choice?
  Currently I am using it when I have JSON services responses: I post notifications and so I have several listeners listening to this type of notification. So far I have almost tens of services to call and let's say many more actions to achieve based on these notifications.
  WDYT?
  Thanks </p>
