The home page of this web site is organized as a "mind map," a technique for visually organizing information. I think of "mind mapping" as a multidimensional framework that serves a purpose not unlike that of a relational database in that data can be arranged according to multiple criteria. The freedom to add branches to a topic as needed provides a ready means to capture and communicate knowledge intuitively.
Apologies for this - lets call it purely functional - website. It's goal is to convey information, it's creator an amateur at web creation.
