Use Glinkr for Mind Mapping

 A tool that always helps me with my work is mindmapping, whether it is making a decision about something, or trying to figure out a topic for your dissertation (click on the thumbnail for an example). Glinkr is a web-based mind mapper that can be used to share all over the web. You can add links and notes to each box, and they can be viewed by clicking on the box. It is free to try out in their Sand Box section, but you have to register to save you mind map.
