People steal ideas. That should be okay.
Because in today’s connected world, ideas that spread, ideas that disperse, ideas that go viral have real potential and value. Not ideas that are in your head or those that are known to only a few.
Look at TED—their core purpose is to spread ideas. Can someone copy an idea and create value from it? Sure they can. Would you call them stealers? Of course not.
It is the age of idea diffusion, not concentration.
