You have an idea. Why not quickly put it out there and have others help you shape and develop it? It’s fun, stimulating and rewarding. You could even find collaborators to help execute on it, or maybe sell it when fully developed.
An idea publication website. Make it easy to publish your idea. Others will see it, rate it, and some will join in and help you shape and develop it. There could be a marketplace for buying these ideas, and a whole system for helping to execute them (finding funding, collaborators, etc.)
