Systems and methods facilitating authoring and problem solving by joint contributors working separately but against a common goal. On-line asynchronous distributed authoring and problem solving system, method, and computer program for focusing attention toward particular authoring and problem solving topics using a threaded discussion group and reward matrix. System, method, computer program and computer program product for coordinating the activities of a plurality of people, where the plurality may be any number from two to thousands or more people. Mechanism for directing the attention and focus of large numbers of people who are solving problems using a tree-based problem space, where the tree based problem space may be a virtual problem space. Algorithms and procedures for evaluating nodes in the virtual problem space and assigning values via a pay-off matrix that serves to focus the attention of large numbers of problem solvers. Combination of threaded discussion groups with the pay-off matrix and a variety of algorithms to create useful system for solving multi-level problems leveraging human expertise.
