5% goes to a development/marketing/projects fund
I must disagree. When you start separation of funds for development/marketing/projects, you are creating employees. Employees lack passion. Motivation always going down. They think how to earn more money, and not how to improve system. Better ones, those who do think of improving system, feels under-rewarded, and hence don't give the best of themselves…
Bitcoin is the best idea. Open system that anyone can improve inside his own ideas, capabilities and needs. Passion for personal success through improving the system is much stronger force than any reward “given” through corporation hierarchy
I don't think monetary incentives themselves are guaranteed to produce substandard products, generally well aligned incentives will encourage cooperation and motivation and produce superior products
