Do you run your own company? It would be interesting to compare side-by-side the benefits of working for Facebook/Google vs. being the CEO of your own startup. Comparing salary, benefits, and perks would be cool, but I'm also wondering if most CEOs find their work more or less interesting and challenging that engineers at these companies do.
