Crowds can't have "wisdom" by nature of the averaging that must occur for binary choices/responses from a crowd.

"Knowledge of the Crowd" is the correct phrase as the storage capacity + experience is greater the larger the crowd.

In other words, you can use a crowd to ask questions that the whole does not need to answer: "Has anyone every done X before?" but you cannot use them to ask questions they all should reply to: "Do you all want to do X?"
