Did you know that Facebook has a way to download all of the data they know about you?   I say “all”, but I’m pretty sure this is only a small percentage of what they’ve accumulated about you since joining Facebook.

Still interesting to read though!

To download a copy of your Facebook data:
  1. Click at the top right of any Facebook page and select Settings.
  2. Click Download a copy of your Facebook data below your General Account Settings.
  3. Click Start My Archive.
