Google Docs.

I didn't exactly tried to do anything in Google docs. I just tried to explore few sites and played around with it. It is nice in a office setting when you're in a same committee but not in the same room. I can see sharing documents or websites can be helpful with Google Docs. It provides service where you can create, store and share documents, spreadsheets and presentations. You can work on your own or collaboratively. You can also import docs from MS Office and Open Office. Useful & helpful
