It's probably no secret by now how much Facebook has on you, with or without your knowledge.
The world's largest social network on Monday announced a new feature created to serve as a single destination for reflecting on past moments shared with friends and family. According to Facebook, it felt the need to add a feature like Memories since more than 90 million people every day are using On This Day to remember the moments they've shared on Facebook. But that's nearly random and sparse.
The Memories feature is available either through the Memories bookmark on the desktop or in the "more" section of the Facebook smartphone app.
Memories are really powerful.
As you might expect, you can control which moments appear in Memories, so you don't have to relive the pain associated with an ex or the loss of a family member.
Facebook Memories will include more than just what happened On This Day a year or more ago. You'll also be able to see "friendversaries" - an otherwise painful way to say when you and one of your friends connected on Facebook - seasonal and monthly recaps of memories wrapped up nicely in slideshows or videos, and any memory that you might have missed that Facebook thinks you should be aware of. The feature is still rolling out to users globally, so don't panic if you don't find your memories anywhere yet.
