The trouble with brainstorming is that it reduces people into 
impersonal little thought bites, little sound bites. It doesn't allow 
them to access their imagination the way they can with avatars, and 
it doesn't allow personal emotional investment. Its emphasis on 
nonjudgmental positivity prevents animus and its bitter, exciting battles.

Brainstorming, with its image of storm troopers from faceless 
military platoons or free-associating advertising drones, encourages 
hivemind rather than originality.
