The document discusses how Yahoo! held internal "Hack Days" where employees innovated by developing new software and services ("hacking cultural 'software'") or improving facilities ("hacking facilities 'hardware'"). Seeing the success internally, Yahoo! is now extending the Hack Day concept externally by partnering with developers through the Yahoo! Developer Network to help them build applications using Yahoo!'s platforms, services, and infrastructure. The Yahoo! Developer Network provides web services, SDKs, and other resources to allow external developers and partners to create software and services that integrate with Yahoo! properties and leverage its scale, social capabilities, and expertise.
