Web 2.0 mindmapping tools

You have been mindmapping for a while, perhaps using a Windows based tool such as MindMapper. But you want to share you maps online with others and simultaneous edit. Like you can documents with Google Document. What to do? Check out one of these online mindmapping tools that my friend Jim Collins alerted me to below. Many are in beta so be sure to backup any live maps you create! Does any one have a favorite or know of any more online mindmap editors?
