Our experiences suggest that, despite promise of navigation, there are significant challenges applying these techniques domains end-user Due features domains, individuals may misuse community data when making leading incorrect individual inaccurate data, "herding" behavior an example what economists term informational cascade. understanding this phenomenon terms, we develop present general approaches mitigating herding support management, mitigation via algorithms user interaction. Mitigation interaction novel cascades systems.
