What is the difference between "browse" and "mindmap"?

Depending on preference, users can gain access to Wonderville's content through two modes - Browse and the mindmap (note that the mindmap is not available to unsigned-in guests). In Browse mode, content is accessed through a more conventional, linear front. In the mindmap mode, links to interdisciplinary content that is associated with a particular topic is displayed. Each mode accesses the same content, but the navigation and display differs.
