It seems that helping people is more and more in the air. I have been working on such idea before google sent this appeal. I am wondering how they will handle the finalist. Do they give you 10 millions and let's say 50% of the shares or do you become somehow a google employee trading your best idea for a jumpstart in the startup area without guarantees of what you will own?
