Ajax Mind Maps

AJAX | WCM | WEB

I am a real fan of mind mapping. As well as a thinking aid and information management tool, I think they could be an excellent interface for navigating the mind blowingly large amount of material on the web. I got very excited a few years ago when I discovered Inxight's StarTree Viewer (there is a fairly unimpressive NASA demo), but nothing much seems to have happened with it. With the rise of Ajax and hugh leaps forward in web user interface, I don't really understand why there isn't more exploration in this area. So, two questions; [1] Is anyone developing a web tool for creating mind maps (equivalent to the open source Freemind software I use)? [2] Is anyone exploring this style of interface for presentation and navigation on the web? Bill Scott's Mind Mapping Design Patterns is the closest I've got so far, here he uses mind maps to describe design patterns, but doesn't bring the two together. Can anyone help?
