10 to the 100 idea network

I decided to start with an idea inspired by the concept of 10 to the 100.  I think an idea like this might go over pretty good in the voting portion of the competition.

What one sentence best describes your idea? A network for people to contribute, discuss, give/receive feedback, and modify ideas to change the world, and maybe find others to help.

1. 
   
2. Describe your idea in more depth.The problem with for profit ideas is that people hold on to them and guard them -for fear of getting stolen- so much, that it is detrimental to the idea. But, if the idea's objective is to change the world for the better, then you want the idea to be heard. There is a need for a social, community website where people can contribute, discuss, and modify ideas on how to change the world. People could come up with the concept and be able to hammer out the details together, and perhaps find help from other members of the community, for the idea to become a project. But, it should't end there. After an idea becomes a project, there should be a log of how the progress of the project is coming along, what hardships the participants encounter, what successes they achieve. It would be great for people with similar idea to learn for their mistakes and alter their idea based on the results of other projects.

4. What problem or issue does your idea address?There is no real network of people to receive feedback and find like minded who may want to help them in their cause to change the world for the better.
