What is it Paper? According to its creators, it is a new way to interact with Facebook.

We carry several days testing it and the truth is that interaction with Facebook improves (and much) you no longer have the standard 'wall' in which the stories occur at furious pace but that everything is much clearer, you can make a kind of "lists" interests and the application anger by placing items so that you can read them.

Management is one of its strongest points, is handled with one hand and at a speed more than acceptable, can do "like", make comments and send articles that you seem.
