To share a group of items, all you have to do is put them all into a folder and share the folder. As you’d expect, if you add an item to a shared folder, it will automatically be shared and if you add someone to an existing shared folder, they will instantly get access to all of the folder’s content.
Google Docs is already an awesome online document sharing tool. But the addition of Shared Folders makes a great tool indispensable. Now instead of sharing doc by doc by doc, you just share a whole folder of whatever you like.
Perfect for projects with related documents and groups that span 2 or more organizations.
Microsoft keeps improving their Office Live service, too, but Google’s got them beat on ease-of-use (though Google could still stand some sizable improvements).
Say what you will about cloud computing, but this kind of incremental development is what makes the cloud so compelling.
