Give me my data app allows users to retrieve their personal information on Facebook.

Recently, Facebook has proceeded to remove users personal information that they have spend years to built, from their profiles to make room to its newest project called " Open Graph."
With that latest initiative Facebook plans to connect users to others people, places, and things across the entire Web. It is part of the much more buzzed about "Instant Personalization" project which is Facebook attempt to link with as many Web sites as possible by letting them install its "Like" button. With that button, Facebook users who visit those sites will have the possibility to click on it and have the page in which it was in, linked to their profiles and have all their friends made aware of the action. More of that Facebook Instant Personalization project can be found at this previous post.
Facebook removal of users' personal information from their profile interfaces has been met with a lot of negative feed back from perplexed users. The good news is that that information is not deleted, it is just removed and moved to a place unreachable by the new interface. But with the whole thing done without any explanation from Facebook to make its users understand what is going on or to give them the necessary tools to retrieve that information, it did not take long for confusion to reign in. Fortunately, there is a little known app called Give Me My Data created earlier this year and available at Givememydata.com that walks people through the steps of retrieving their data. And according to the New York Times, the free app will let users retrieve not only their personal information on their profile pages, but a variety of their Facebook data making it possible for them to make copy to be saved somewhere else.
