"Kasparov versus the World is a fascinating case study in the power of collective collaboration. Most encouragingly for us, Kasparov versus the World provides convincing evidence that large groups of people acting in concert can solve creative problems well beyond the reach of any of them alone.
More practically, Kasparov versus the World suggests the value of providing centralized repositories of information which can serve as reference points for decision making and for the allocation of effort. Krush’s analysis tree was critical to the co-ordination of the World Team. It prevented duplication of effort on the part of the World Team, who didn’t have to chase down lines of play known to be poor, and acted as a reference point for discussion, for further analysis, and for voting.
Finally, Kasparov versus the World suggests the value of facilitators who act to channel community opinion. These people must have the respect of the community, but they need not be the strongest individual contributor. If such facilitators are flexible and responsive (without being submissive), they can co-ordinate and focus community opinion, and so build a whole stronger than any of its parts."
