A repository of references to inspirational content that sparked novel ideas in people and is likely to do the same for others.
People would add links to videos, articles, books,... and quote the timestamp/text that sparked an idea in their mind. They should aim to describe their exact thought process at that eureka moment. They could specify which other pieces of knowledge influenced the final idea. Ideas are often remixes of various pieces of info and circumstances.
People would write a brief story on how they came up with their idea and links/quotes of the most influential factors.
The repository could be useful for drawing new conclusions about ideation, finding new patterns, or learning from each other's thought processes.
Integral part of an existing ideation platform
Something like this would make sense in a place where people talk about ideas. It could be integrated into an existing platform (like this one) as an optional field "How did you come up with this idea?".
I noticed that in our idea descriptions we often provide credit with "this idea was inspired by <link to other idea>". What I propose here is to make this more elaborate and add a dedicated section for it.
Inspirational content rating
The entire repository could be useful to ideators as idea starting material. They could browse through the links that inspired other people's ideas in hopes that it could do the same for them. Sort of like a fishing expetidion for sparking creativity.
People could rate each idea starter based on what it did for them. Underneath each reference there could be a button "Did this inspire your creativity?" yes/no
Based on feedback, the most idea-starting content would surface to the top of the list. Such a repository would then be an ideal tool for jump-starting creative thinking.
The repository would have to be moderated to keep self-promotion and spam at bay.
