Microsoft's FUSE Labs today released a new beta Facebook app from FUSE Labs called "Docs".

Built on Microsoft Office 2010, the Docs app enables Facebook users to create and share Microsoft Office documents directly with their Facebook friends, using the Office tools they already know.

Documents can be created directly within the app, or can be uploaded from your PC. After starting work on a document alone, you might then choose a few others with whom to share it. Or you might instead share it with all your friends, or you might share it with the world. Documents can be viewed and edited directly within a web browser ? or, with a single click, you can edit them more powerfully through the Microsoft Office software on your PC or Mac.
