Rule #5: Be Bold!
One of the first rules that entrepreneurs learn is that investors don't like revolutionary new ideas. Even when they work, the reasoning goes, they won't make you any money. Instead, investors want to see "innovative" ideas: ideas that push the existing envelope a little further, but don't totally change the map. With free culture projects, however, the situation is precisely inverted: people don't get as excited about contributing to merely "innovative" projects, they want to make "revolutionary" change in the world. High ambitions attract good company, and free licensed projects will do better not to set their sights too low.
