"A good Idea is worth a trilllion dollars......"

Back in 2008, Google did a "10 to a power of 100" contest for best ideas for charity and 160,000 responses were submited.

What i dont understand is why didnt they maintain a on-going site to allow people to 

constantly list their new ideas, thoughts for constant discussion, improvement on others ideas, and even fruitful collaboration

and actual business ventures on these ideas.

I think it is crucial Facebk should have a IDEAS page on the Cause site, structured in a way that similar ideas in each charity category

are aggregated and summarized in bulletpoints once every 3 mth(like what google did in the contest)

.And with a msg bd or twit stream open for discussions on constant improvement of these ideas.

People have charity ideas all the time but there is simply NO reputable site or widely recognized site out there that they could post and get feedback.

And a lot of the ideas are already out there, being executed by ongoing non-profits.  It will be very nice if one could just

come to the site, submit their new idea, and do  research on the site  and see if that idea has been done or is similar in nature, and could then get the contact info on the people to collaborate the similar idea with, or just read other similar ideas and see if one could improve on them.
