Mapping

All possible ideas
Non-linear in development and presentation
Non-judgmental
Most general to most specific
More information than necessary: choose only the best
Multiple uses: find topic, explore aspect of topic

MindMeister (collaboration)
bubbl.us
Mindomo
Comapping (collaboration but linear)
