I enjoyed reading the scenario Andres. fun pics as well; especially the dancing ones :P
i'm thinking how one can make it even easier, such that more & more people want to be at the place in the right time.
or let say it like this: imagine one posts a problem on the wall of a facebook page which has lots of visitors, "HOW AM I GOING TO REPAY ALL MY COLLEGE LOANS?"
what will be the result? how will those large number of people react? would they share their own experiences? might there be some people who had some idea as well? or not?
now what will happen if in a central metro station where there're lots of people waiting for the tram, there exists some simple walls for writing & posting on it + a written problem: "HOW AM I GOING TO REPAY ALL MY COLLEGE LOANS?" what will happen in this case? would anyone contribute?
I'm thinking this way so that we may come to a spontaneous system. since if it depends on some organization and lots of budget, it may not be that simple to handle.
The concept is simply written, instead of making a platform only for invention or innovation; let's make a common space where everyone enjoys to be. and then feed them with good inputs; such as inventions as mentioned in your idea, or problems, or any other thing that may trigger the spark. ha?
