Is this a classic of the later adopters finally seeing the light? These etherpad-like tools have really proliferated since Google bought the original etherpad and then released it as public code. Now folks are beginning to pick up collaborative writing in business and education so the curators begin to 'discover' them. Prophets in their own country and all that. I remember how I tried to open teachers' minds to Twitter when it first came on the scene, but they politely listened and walked away with great big, "meh."
So learn again my friends and let Robin Good instruct you once again in the beauties of real-time, collaborative writing that can be asynchronous as well.
"Robin Good: Titanpad is a web-based collaborative document editing tool that allows any number of people to work collaboratively and simultaneously on the same document.
Every user gets automatically a different color, there is no need to sign-up, and best of all there are infinite levels of Undo and you can have a dedicated subdomain where to host your collaborative docs.
The service is free. Find out more here: http://titanpad.com/ "
