The other day, I released a mind mapping gadget for google wave, and its proven to be quite popular. Popular for something I knocked together quickly anyway. There's an active wave discussing features, which also serves as the main description of the gadget. Its getting a bit long now, and I'm aware that there is a limit to how big waves can get before they start to slow down. It also gets to the point where I want to simplify things so that a new reader coming upon the wave doesn't get confused by the threads of conversation there.
