This is a website providing online mind mapping that was just discovered today. I once imagined software like FreeMind, and thought it would be amazing if it were made into a web application. I even hoped for a while that Google would create something in this area (GFans :)). It turns out someone has already come up with a beta version. Since it's from overseas, the speed isn't great, so I haven't looked at it in detail, but judging by the interface, it's pretty good. Another Web 2.0 application. I wonder if Google will acquire it; this should also be part of the Office family.
