DeliciousMind = del.icio.us + MindMap

A developer who is a big fan of the social bookmark application del.icio.us and the open-source mind mapping software program FreeMind has created a "mashup" of the two called DeliciousMind. It enables you to easily import del.icio.us bookmarks and display them in the nodes of a visual map, complete with hyperlinks. I'm not a user of FreeMind, so I haven't had a chance to check it out, but it does sound mighty intriguing!
