Social Memories sucks down your Facebook data from June 2009 onward, visualises it with graphs and charts and shit, makes albums from your pictures, and turns it into a book you can buy with actual money. It lets you know which of your status updates, photo albums and pictures are most popular (hint: the naked ones), when your friends birthdays are clustered, where your friends are from, who you take the most pictures with, and a bunch of other useless data that's still quite fascinating to look at, especially if you are self-absorbed.
The most interesting thing about it isn't what you'll learn about your friends (who are lame) but that you are quite banal. Or at least I am! Why, just look at my most frequently used words. Sadly, it is not set in Helvetica. I expected more of the Germans.
