Here are some other statements about Franklin from Wikipedia which might illuminate the meaning (and maybe Norvig's assessment of the quote's relevance to computer science, information retrieval and Google):
Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In a Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat."[3] To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."
Franklin never patented his inventions; in his autobiography he wrote, "... as we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously."
His inventions also included social innovations, such as paying forward. Franklin's fascination with innovation could be viewed as altruistic; he wrote that his scientific works were to be used for increasing efficiency and human improvement. One such improvement was his effort to expedite news services through his printing presses.
