"What if a big company copies your idea and develops the same website as yours after your website goes public?"
How can I answer this question?
No, the question is: What are you doing now knowing that a big company will copy your idea?
No, wait, the real question is: What are you going to do when another smart, scrappy startup copies it, and gets $10m in funding, and is thrice featured on TechCrunch?
No, wait, I'm sorry, the real question is: What are you going to do when there are four totally free, open-source competitors?
No wait, I forgot, actually the question is: What happens when employee #2 makes off with your code and roadmap and marketing data and customer list, moves to Bolivia, and starts selling your stuff world-wide at one-tenth the price?
