From another Diigo group - this is a suite of fun tools from the BBC for organising ideas and generating new ideas. In Pinball you will find tools for creating mind maps, outlines, and simple slideshows. Pinball also has tools to help you brainstorm and generate new ideas.
Richard Byrne's blog. "Coggle is a new, collaborative mind-mapping service that is very easy to use. To create a Coggle mind map just sign-in with your Google account and click the "+" icon to start your mind map. After entering the main idea of your mind map you can add branches by clicking the "+" icons that appear next to everything you type. To re-arrange elements just click on them and drag them around your screen. "
