As it has been mentioned before, you can share the memories that you well get with Patch 1.21 and the Generations EP in Facebook and your Sims 3 profile.
Once you’ve uploaded a certain amount of memories, you will get a Badge AND an object from the Sims 3 Store for free. Check your purchase history, you won’t get a message about them
You can delete as many uploaded memories as you like. They still count towards the total
|1 Memory||5 Memories|
|10 Memories||25 Memories|
|50 Memories||100 Memories||200 Memories|
Pictures of the badges can be found here: Badges
