A brilliant, 'must try' web tool for group to text/voice chat, with a collaborative whiteboard, document viewer and more, all in real time. I'm really loving this tool at the moment for joint language lessons with my school's Chinese partner school. No sign in require, however register for free for extra features.

"A great, simple, collaborative mindmapping site. Invite other users to share ideas together in real time. It uses html which means that you can use it with most web enabled devices. Sign in using a Google account."
The absolutely great thing about Twiddla is that you DO NOT have to sign up. They will automatically create you a guest login but you can still create a meeting on the spot and invite attendees. It is easy to use and a great place for collaboration.

You make some very good points but I think you could go further. The reason we put so much emphasis on "originality" is because we were preparing students for a world in which they would have to prepare written and oral presentations individually. In the modern workplace, very little is done that way anymore. Authorship is not what it used to be. Now, everything seems to be collaborative, generated at "stand-up" meetings of the whole "team". I'm not sure the end result is better, but it's clear that the very concept of plagiarism needs reconsideration. What if we created exercises around the task of correcting other people's work? Wouldn't that be more useful and "creative"?
