One of the virtues of mindmapping is that it has the capability to depict information in non-linear fashion.
Mindmapping has been taken to a new level with Personal Brain software from TheBrain.com.
This version of mindmapping is more than a mind map, as it is an information management tool that de-linearizes the process of storing and retrieving information. This type of interface would also be a great way to categorize and find trends.
What is especially cool is that these folks have created a web portal for users to upload their ‘brains’ for others to see.
Think of it as a next-generation Slideshare.net on caffeine.
