TitanPad is essentially a clone of the original EtherPad. With TitanPad anyone can instantly create a collaborative document. You do not have to create an account to use TitanPad, in fact creating an account isn't even an option. To get started just click "create public pad," enter your name, and start typing. To invite people to collaborate, just share the url assigned to your TitanPad. Every collaborator on TitanPad is given a unique color to highlight the text they've added. Try it now on this document that I started.
Applications for Education TitanPad could be used as a platform for quickly hosting and recording an online brainstorming session with your students. As accounts aren't necessary you won't lose any classroom time to getting students through a registration process.
Wiffiti (http://wiffiti.com) allows students to submit a text message to an online bulletin board. Messages can also be submitted to Poll Everywhere, but the Wiffiti board is large and animated and students love the fake names it assigns to their posts. ..
