Broadcasting Ideas

Why don't you broadcast your ideas?
I use this word "broadcast" just to give impression on the effects of ideas, even a simple one. Once an idea has been launched into public it moves like a wave from a centrum to the edges. And it multiplies itself. Look at the waves created by a little stone plunging into a still water in a pool! The similar event could happen to our broadcasted ideas. They can resonate similar ideas of other people, or stimulate them to the next one.
