Its really nice to see so many people agreeing on putting your idea out there. I am in the process of building a web portal (http://friendvestment.com) that allows people to share their ideas/startups looking for financial/technical partners. While building, one of my main fears was that most of the new people will worry about sharing their "big" idea and ask for security, etc for their ideas. But the fact that an idea has zero value if it is just an idea, seems to be resonating a lot these days through people...
