Such a good question! It illustrates how for ideas to flourish they need a platform and strategy to be organized and improved upon.

For example there's a great innovation tool called the Lotus Blossom Technique - you start with a concept, but then add layers of ideas or improvements to the original idea (like peeling a blossom) until you reach a core (and much improved) idea. The results of this are much more effective and targeted than traditional crowd-sourced problem solving - such as via forums - that can often involve lots of orthogonal voices shouting ideas yet lacking structure.

I love the Lotus Blossom as a creative thinking tool, yet can imagine on a larger scale it's an issue in itself to organize (e.g. who leads the process? how to make everyone feel 'heard'? how to keep the brainstorming on track so ideas are strengthened, not watered down?) So, when it all boils down, it's understanding and adapting to human psychology (at both an individual and collective level) that solves large-scale problems. This would be an awesome problem to solve!
