In business, invention is often said to be overrated as compared with execution. Perhaps the best proof of this idea yet to be offered by the twenty-first century is the success of Facebook, a business with an exceedingly low ratio of invention to success. There is no lightbulb, or telephone, let alone a truly ingenious algorithm in the company’s history. And yet no firm, save Google, has harvested as much attention from the Internet, or commercialized it as effectively.
