Microsoft Started Office Document sharing online site Docs.com with Facebook. People have to login using Facebook. Then user could create, share Microsoft Office Document file among their Facebook friends. It’s actually like Google docs, just they used Microsoft Office Technology. This is still closed beta. Check Docs.com
You log into Docs using your Facebook account. then, you can view shared documents. The service is currently in a fairly early beta stage, meaning you’ll have to sign up for their waiting list before you can upload or create your own documents. Because of that, there’s not much to the service now, but it’s clearly a push toward competing with Google Docs. If you want to Edit or create files online you need to have Microsoft Silverlight, so it will work best in Internet Explorer.
It seems Microsoft is teaming up with Facebook to fight Google. let us know your thoughts on this and what you expect more from this Docs.com
