Discussions In Google Docs.
Google today introduced discussions in Google Docs. With this feature, we want to encourage rapid and seamless discussions, help the right people participate, as well as integrate discussions with email in an intuitive way. For a look into the way discussions work in Google Docs.
Now you can easily tell who made a comment and when—with timestamps and profile pictures—and you can keep track of the conversation with email notifications and reply to comments directly from your email. Your discussions will be better and so will your documents. And all of this is possible because Google Docs lives in the cloud.
