Despite countless changes to the social media site, Facebook's notification tray has remained the same. An update in the near future however will soon allow for personalized "notification cards." These cards will act as little reminders that users will find on their notification tray, which will alert them for a variety of reasons. For example, if a user likes a TV show, a card will appear notifying them that a new episode will air tonight.
Users will be able to fine-tune these cards to their liking, or disable them all together. More personalized cards include an event notification for something that you may have sent an RSVP to months ago, or if a friend is in town, Facebook will send you a card. The Facebook notification update has been in the works for a while and will follow a pattern in social media centered on hyper-personalization.
