Piggydb is a knowledge building application. You can think of it as a mix of notetaking, outliner and concept map all together, but with the flexibility to do more than that. Its non-linear system and bottom-up or heuristic approach gives you the possibility of creativity to discover new concepts and ideas based on your input. There is no wrong way of using Piggydb. It helps you to elaborate your own knowledge.
