Efficiency in Growing Markets
"In a rapidly growing market, you don't worry too much about efficiency. It's more important to grow fast. If there's some mundane problem getting in your way, and there's a simple solution that's somewhat expensive, just take it and get on with more important things. eBay didn't win by paying less for servers than their competitors."
