If I'm understanding correctly, this method is for randomly finding "creative ideas" but contains no way to direct those ideas towards solving any specific problem?

I usually consider creativity useful only when I can target it towards something I consider a worthwhile problem. Trying to realize a random creative idea would distract me from focusing my efforts on problems I've already found to be most important to work on.

Still, this does sound like it has potential- the more people using this, the chances that somebody would think of something related to a problem I am personally trying to solve would become higher.
