I think this is not really new but it looks like a lot of people don’t know about the new service of Microsoft called Docs.com. Docs.com is a kind of a online Office Suite connected to Facebook.
You can simple upload or create Microsoft Office files and share them with your Facebook friends. I think this is the first time Microsoft gets his Google Docs rival right. It’s very simple to use and you can login and share documents with something nearly every person has.
