Having a lot of ideas is much better that having none. It is never a good idea to keep an idea to yourself in fear that the rest of the group will think it is stupid. This small ideas may not ultimately have anything to do with what you are trying to accomplish, but they may be able to spark an idea in someone else. Thats what it takes to get things going and develop solutions, spitballing and picking up where the last person left off. Now with the advances of the internet we are seeing groups form of an exponentially larger group of people then could ever be possible without technology. This abundance of cross global communication is what has led to many of the modern advancements that we see today. Now we are able to use platforms such as openideo to solve problems elsewhere, much like the sanitation and drinking water challenge. Where many people across the globe don't have basic conveniences that most of the rest of the world takes for granted. So we as a global community are coming together to figure out what solutions are out there as a possibility. We are bringing all of our different types of knowledge and culminating them to lead us to one final product, after many different people submitted their contributions.
