Internet Applications: Mapping the territory

Why map? To help understand the space of existing applications and the technologies they use. To identify areas of high activity – where the action is. To identify areas of low activity – where there are market gaps. A kind of business intelligence.

Maps have dimensions A physical map has latitude, longitude and height Maps have a purpose – geographic, political, historical, energy usage… Conceptual maps need dimensions too.
